Hello. I have a stock suspension '97 Disco 1. Can I fit 225/75-16 tires in without trimming? If I can, will they look small when I get enough money for OME HD springs and shocks?(1 1/2 - 2 in. lift)? I need new tires in a month or so, but I don't have enough money for the lift right now. So I don't want to get new tires that will be too small for my lift in the future. Oh, one more thing - Will I lose a noticable amount of power from the very slightly bigger tires? If any of you have done the OME suspension lift with no other mods, can you please link me to your pics? Thanks a ton!!!

you will need no trimming.

they will looks mall in my opinion after the OME lift.

consider the 245/75 + trimming

Thanks for the info, Rob. I'm doing this research for my bro, and He's a bit paraniod of taking a saw to his precious Rover, but I really want to improve his off-roading capabilities. If we do decide to do the 225/75 anyway, will we have to adjust the steering bumpstops or anything else, and how much do you think getting the spedometer and odometer adjusted would cost at a shop, or can anyone link me to instructions on doing that? Thanks.

Hold up a second........225/75/16?? Does he have a Buick? Don't disrespect England like that boy! Ok seriously, I don't think anybody makes a good tire in that size and that will really look small even without the lift. Way too skinny in my opinion. Go for a 245/70/16 and it won't rub and will look ok when the lift is put on. I think you can actually even fit a 255/70/16 without any rubbing. I think you would be extremely disappointed even if you were able to find a decent tire in a 225/75/16. Tell us what kind of tire he wants and a price range and we can hook ya up with something nice.

Well I take that back, you can get a lot of tires in that size, although I doubt many tire stores stock them. Other than this moot point, I am sticking with my previous post.

Matt, What tires do you recommend? I am in the marked for tires right now. I have a stock 99 D1. I am looking for a snow/off road tire. These will be only used for winter and offraoding. I was also looking at the 225 75 16. There where not too many tires out there in the stock size and I do not want to trim. My rig far exceeds my offraoding abilities right now.

Well Brian, a lot of this depends on the amount of snow. I don't blame you for not wanting to trim, and I would probably go with a 245 70 16. Personally, I think true all terrain tires are mud tires. However, mud tires without siping (the little grooves in the tread) are really scary on ice. The Pro Comp MT has siping on the center tread blocks, and therefore will do ok on ice. The BFGoodrich MT seems to be a favorite, and I have first hand experience with the Bridgestone Dueler MT and have no complaints. Additionally, the Goodyear Wrangler MT/R gets good reviews. If you are stuck on 225 75 16, I would get the Dunlop Radial Rover RT. It will go well in snow and ice and get traction almost as well as the true mud tires off road. For about $20 per tire cheaper than the tires mentioned above, it is a great value to boot. If Futura makes an Enforcer MT in that size, it would be a close second, although they might be being phazed out of production. Check out tirerack.com and browse through some of their stuff.

Joel, when I bought my 96 D1 it came with Goodyear Wrangler ATS 225/75 16s. The 225/75 16s are the same height as the stock 235/70 16s (29.5"), the only difference is obviously the witdth. The 225s are an inch narrower than stock, and I didn't like the look. They looked like bicycle tires on my truck. Since I couldn't find a decent 235/70 16 all terrain tire with a reasonable price, I went with the 245/70 16s. They don't require any trimming. FWIW I have BFG ATs and I am really enjoying them. I don't know how the 245/70s would look with a lift. If I remember correctly, when I was researching tires and sizes on this website I believe lifted trucks with 245/75s required some trimming due to the tire width.

My Green 96 disco has the OME 2" lift with 245/75/16's. They don't rub and look pretty cool. The pic in my profile was before I added the rockware shock mods, but after the lift. My White one also has the OME 2"lift and has 255/70/16's, and they only slightly rub on a very sharp turn, but I haven't had that one on any severe enough trails yet to see what they will do when she's twisted.
And Joel, I'm goin to UVSC, if ya ever make it up here to Orem to go wheelin, let me know!

Easy boys, easy! Give that chap a chance, please!

* 225 are not an inch narrower than stock, they are 10mm narrower (less than half an inch narrower).

* 225/75-16 are taller than stock. Do the maths, and you'll see it is approximately 9mm taller than stock 235/70-16.

* 225/75-16 are available in lots of brands and types. It's common size in Europe/Japan.

* 225/75-16 fits without trimming, and should not induce steering stop adjustment (this shouldnt't scare you anyway, it's a less than five minute job).

* You can fit taller tyres than 225/75-16. Check John Barge site here: http://members.shaw.ca/jbarge/tires.html

* It is reported you can fit tyres as tall/wide as 245/75-16 on a Discovery without sawing, though it would be wise to check this on a ramp - tyres differ, trucks differ, and you need to stuff the axles as on trail to check for rubbing.

I run 245/75-16 summers (look here:
http://www.sf.hiof.no/~frodehaa/forandringer/245-75.htm ) and 225/75-16 winter.

Roverly Yours, Frode

I try once more:
Are they that skinny?

Seen from left to right:
245/75-16, 225/75-16 and 205/80-16 (stock in some markets).
Are the midsized 225s really that skinny??? I do believe the type of tread deceive a bit - a mud pattern looking wider than a road pattern. Meaning: I guess you couldn't tell a AT or MT 225 from a roadpatterned 235!!!

joel, the speedo is probably off in the truck anyway, the tires will make no practical differnce.

borrow a gps and get the true speed of the truck and you can compare yourself.

the differnce in these tires would be the differnce between worn and new tires. do you ever wonder if the speedo is off when your tires are 1/2 worn?

i would trim if i were you.

the reason for trimming is not seen on the highway . it is offroad when the tires tuck up into the wheel well is when it will rub. you might be fine with the larger tire if you dont go offroad before you getthe lift.

It's been a while since I've looked into it, but Kyle had a non-cutting method for fitting slightly bigger tires, and there's a write up of it in the Tech section ("Rear Fender Relocation").

It's been many long months since I've been able to follow DWeb religiously (back before registration, the "lobby" and such), so I don't know if this method has continued to prove effective over time. Does anyone have an update of their experiences with it??? It still seems sound to me though and is what I plan to do come summer when I am due for some new tires (I have been running OME HD for about 18 months now and those stock tires are just looking too dang small in there!).

Just watch for availability Joel, I don't know any shops in the area that carry 225/75-16's, or 205/80-16's. Both sizes would be a special order tire, at least in the state of Utah, and that's not always what you want if out wheelin and a rock punctures your side wall. The first common size you would come across would be 235/85-16 (these are too tall and skinny in my opinion, mostly used for farm eqip.). But if you can fit the 245/75-16, that's the stock size that comes on most chevy trucks and suv's, so any shop would have an abundance of them in new or used.

Frode, look at the specs between the GY Wrangler AT/S in 225/75-16s and the Michelin Synchrone 235/70-16s on Tirerack.com. You'll notice that the data is in inches and the overall diameter of the two are exactly the same, and the section width is 1" narrower (GY ATS = 8.8" vs Mich 4x4 Synch = 9.8"). There is some variation among the different types of tires for a given size.

Lawrence, I have used the fender relocation method for about a year now, and it has worked flawlessly. But I wouldn't suggest it if you are going to go bigger than 235/85; it then becomes very difficult to bow the aluminum out enough. And if you do get it out that far without damaging something, from the rear your truck will look like it has ears. :-)

Adam,
My rear bumper already has a slight smirk to it, so I guess ears wouldn't be THAT bad. ;-)

Seriously though, thanks for the input. I am mostly leaning toward 245/75 myself, but I really do like the look of 235/85s. I don't think I'll ever go bigger than that as long as the rig is my primary daily driver.

Chris W:
Inches are very rough compared to the new invention of millimeters (there is 25,4 millimeters for each inch), which is reason why millimeters are way more useful for measuring skinny tires like those we're talking about here:
Check sizes on this calculator
http://www.expeditionexchange.com/tiresize.htm
The maths are clear, but as you may have found: brands and types do differ; sometimes to a large degree. This you would have to check anyway, whatever size you choose. Example you chose: 9.8inch section width is more like a 245/xx tyre than a 235/xx according to maths and other makes. Browsing other tyres you might find other peculiarities!

IMHO the only reason that you have not needed to trim a D1 when running 245/75R16 or larger is because you have not articulated and stuff a rear wheel. Eventually you hit a rut or something that rub. It does take much to clear the 245s. I just had to trim the lip of the fender, nothing that went up into the body or anything.

Comparison of 235 vs 245 are in my gallery with about 1.5" lift.
