Author Message   Rick Lindgren Posted on Wednesday, March 13, 2002 - 01:03 pm:    I own a '99 DII and I was thinking about putting on 245/75-16 Dunlop Radial Rover R/T�s. However, Dunlop only "recommends" the 7-inch rim for the 245/75-16 and the DII has an 8-inch rim. I am largely a tire ignorant and want to know how strict this recommendation is. Should I be concerned? Will a tire dealership mount them on 8-inch rims? How does it effect the tire if mounted on 1-inch wider rims? Does anyone have the 245/75-16 Dunlop R/T's mounted on their stock DII? If so, have you had any problems? Any input would be appreciated. Finally, if someone has these mounted on a stock DII (no lift) could you post some pics so that I can see how well they fit the wheel well? Thanks, Rick   Eric N (Grnrvr) Posted on Wednesday, March 13, 2002 - 01:05 pm:    I could be wrong but, can't a D2 fit 265/75 tires with stock suspension.. I have a D1 so I'm not 100% on that but, I think that you can..   Leslie N. Bright (Leslie) Posted on Wednesday, March 13, 2002 - 01:06 pm:    Hopefully someone can chime in who HAS done it, but.... FWIW, mi dos centavos.... The TreK DII Discos used 245/75R16 tires. They were BFGs, but I don't think that that would make a difference. I like the Dunlop R/T, BTW.... -L   Leslie N. Bright (Leslie) Posted on Wednesday, March 13, 2002 - 01:07 pm:    Hmmm.... Good point, Eric. The R/T is available in that size... http://www.dunloptire.com/tires/Rover_rt.html -L   Rick Lindgren Posted on Wednesday, March 13, 2002 - 01:20 pm:    I saw that the 265/75 are recommended for 8-inch wide rims but I seem to remember people saying that they rubbed a bit. Maybe that's not true for the DII. My wife, kids, and I "share" the disco. They have it during the week (mostly on-road) and I become Captain on weekends, holiday, etc. So I'm trying to get as much off-road performance as I can without modifying the heck out of it or forcing my wife to kill me in my sleep. Rick   eburrows Posted on Wednesday, March 13, 2002 - 02:35 pm:    265/75's on a DII do rub 'a bit', but this is easily cured with 10 minutes and a screwdriver. There is a small bracket holding the inner wheel well to the front bumper. It's just a U-shaped piece of metal, bolted to the bumper, and to the wheel well wall. If you unbolt this bracket, and turn it arround, it will hold the wheel well wall forward about an inch. This will cure the rubbing. I highly recommend the 265/75 size for a DII. I did it a few months ago, and I'm super happy with it. Just beware, you will loose some torque from the size increase.   Robb Sundmaker (Robb) Posted on Wednesday, March 13, 2002 - 05:19 pm:    Does anyone know the size of rims on a D1?   Eric N (Grnrvr) Posted on Wednesday, March 13, 2002 - 05:20 pm:    16x7   Will Roeder (Will_Roeder) Posted on Wednesday, March 13, 2002 - 05:22 pm:    16x7....i think....btw rob, you own a red disco right? this is the will with the gold disco 1 that went on the trail ride with you a few weeks ago   Robb Sundmaker (Robb) Posted on Wednesday, March 13, 2002 - 05:26 pm:    Yeah Will. What's up? I just got my Disco out of the shop. Instead of using money for offroad upgrades I spent $900 on fixing three leaks. I almost emailed you last week to go offroad last weekend. I was bored. I am going to go on the trail ride on the 23rd. I am nervous about it because my tires are stock and worn out. I was going to buy tires for it before the 23rd but now I have $900 more of credit card debt. I still might do it though. What tires do you have?   Will Roeder (Will_Roeder) Posted on Wednesday, March 13, 2002 - 05:30 pm:    Ive got 235/85 goodyear MTR's on the alloys(the tires on the truck that day) and Super swamper TSL's 32x9 on steel wheels...p.s. feel free to email me anytime if you want to go on a trail ride, or if you have a question abot the disco.also, whenever there is work needed on your truck, feel free to come over here and i can help you out What tires you thinking about getting?   Robb Sundmaker (Robb) Posted on Wednesday, March 13, 2002 - 05:54 pm:    Will, I will email you.   ravensjk Posted on Wednesday, March 13, 2002 - 06:15 pm:    eburrows... Any chance you can post here, or email me a pic of your truck with the new tires? Are you still running the stock suspension? When my stock tires wear out I am thinking of either 265/70 or 265/75 to replace them. Also, did the new tire size fit on the spare holder?

Al   Dave Posted on Thursday, March 14, 2002 - 09:08 am:    If you would like a pic of 265/75 on a DII (Rover RT's of course), let me kow. I can post a pic of mine...   Rick Lindgren Posted on Thursday, March 14, 2002 - 02:14 pm:    Dave I would be interested in seeing some pics. Are you running a stock suspension or do you have a lift? Also, what are the changes in torque, speedometer/odometer reading, and gas mileage that I could expect if I go from stock tires to the 265/75? Rick   Dave Posted on Thursday, March 14, 2002 - 04:59 pm:    Rick, good questions. I run an OME HD lift. nets about 1.6" in height given I have a bullbar and winch. All of the above have changed obviously. I have not had a chance to verify the odometer/spedometer. I get around 300-320 to a tank on highway. In town is down to 200, but this is with my unadjusted sped/odo. Torque is relative. The rig is still fast off the line and maintains torque. It's still just as solid offroad. I think under 32" tires, and you should be fine with stock gears. 33" and up and you'll need to regear. Pic:   Dave Posted on Thursday, March 14, 2002 - 05:02 pm:    Rick, good questions.

I'll try posting the pic again shortly.   ravensjk Posted on Thursday, March 14, 2002 - 11:43 pm:    Keep trying Dave! Also, a few more questions. - Did the 265/75s fit on the stock spare tire holder? - You mentioned the rub fix in an earlier post, but with the Stock suspension would the the 265/75s be limiting off-road? Thanks, Jason   Curtis Posted on Friday, March 15, 2002 - 02:37 am:    Jason, No - they don't. Some reccomend turning the spare tire holder upside down. This is not the way to go. Simply remove the carrier from the door and drill new holes about 1/2" below the old ones. It will fit with about 1/16" clearance of the bumper. Shown below is the tire rub solution Curtis   Curtis Posted on Friday, March 15, 2002 - 02:39 am:    ah crap - nevermind - I will try to get a pic up tomorrow.   Dave Posted on Friday, March 15, 2002 - 08:49 am:    Curtis, why is turning the spare bracket over and just re-drilling two holes not the way to go? Just curious. I did it and it worked very well for me. Jason, with stock suspension, I would imagine you would be limited offroad. However I can't be certain. You may want to inquire on the yahoogroups, disco2owners group about that. Cheers, Dave   Dave Posted on Friday, March 15, 2002 - 01:09 pm:    Jason, I finally got around to sending Ho some pics of my rig. You can view it in the photo gallery, "David Marchand". The second to last pic from the bottom, front shot of my rig all muddy should give you a good view of 265/75 with OME lift. If you need other pics, just let me know.   Curtis Posted on Friday, March 15, 2002 - 04:57 pm:    Dave, Because it is not just re-drilling two holes and there are some adverse effect. For one, you have to modify the bracket so that the wiper does not contact it. That is not so bad. The thing that bugs me is that it moves the tire to the left - more or less centering it on the door. This is going to place even more leverage on the door hinges. Those hinges are already somewhat problematic and I do not think any more stress that necessary should be put on them. Going to a larger, heavier tire and centering it on the door cannot be good. Just my thoughts though, but it seems so much easier to just drill new holes and move the tire up. Curtis   Dave Posted on Friday, March 15, 2002 - 06:12 pm:    Curtis, I see your point. I guess I went for the easy solution. Has anyone designed a door catch for the rear door? Meaning something to keep it from swinging out and destorying the hinges...   Rick Lindgren Posted on Saturday, March 16, 2002 - 08:46 pm:    Curtis, can you explain what you did to your rear tire carrier? You said "drill new holes about 1/2" below the old ones". I want to be sure that you meant to drill the holes in the tire carrier itself. Will the carrier still fit into the "perfectly shaped" recess on the rear door if you move it up by 1/2"? Also, thanks to everyone for the great input so far. Rick   AL Posted on Sunday, March 17, 2002 - 10:26 am:    All you have to do is drill 2 holes in the body because once u turn the carrier upside down the offset is there to give u clearance for the bigger tire. On the wiper issue, just take the nut off the main nut on the wiper and move it few notches up. Expedition exchange has a write up under tech section. CHEERS
