i see by your posts you are running 255-70-16's.
are you running a lift?
any problems/trimming etc?

thanks in advance!

Stock height, however, I think my truck actually sits lower than stock b/c of 145K miles on stock spring. Without 1.5" spacer the truck does not rub or require any trimming. But you will loose turning radius in the front..... the tire rub the front link-arm. You can fix the problem by adjusting the steering stop. With the spacer, you can do full turns again. The only rubbing I get is from the rear tire rubbing at the edge of the lower rear quarter (the point closest to the tire). However, it only rubs slightly when the truck bottoms out (ie hitting the drive-way too fast) With the fender protector, it rub even more, b/c it adds thickness to the rear quarter. I end up sanding down some of the black rubber on the edge.

I am waiting for John at RoverTym to start production on HD spring with stock height (3-4 weeks)

I used 265-70-16 on my pervious set of tires, no real world height difference btw that and 255-70-16. I will probably stay with 255-70-16.

thanks jason!

you've answered questions i've been looking for quite some time to get answers to. much appreciated. last q, though - did you experience a big mileage drop with the bigger meats? i've heard guys running the 245-75's with a lift drop to about 11mpg. i average about 14-16 now and since it is my daily driver- i really don't want to loose out on mpg (as if that was ever a stong point on these cars!) but want to enhance off road ability as well

thanks again

If it rubs when you are pulling into the driveway wouldn't it rub really bad under articulation when stuffing it up into the wheel well while driving over rocks, ditches, and such?

Eric...it takes a good wack (bottoming out) to rub using the spacer. The spacer moves the rim out 1.5", which at full articulation (total bottoming out) the outside edge of the tire contact the edge of the quarter (where most people trim for clearance) If you don't put the spacer, it will not rub, but you lose turning radius (rather than 3 turns of the steering wheel I got 2.25 turns before the front tire rub) 3 points U-turn isn't so bad.

I averaged 14-15 mpg new 145,000 miles ago, with 255-70-16, no less than 13-14.5mpg. I think the decrease mpg is probably due to stretch timing chain and worn camshaft lope.

Steve - you may want to analyze cost benefit of buying a set of offroad-only rims & rubber.

If:
[(offroad rims + offroad rubber) + (new onroad rubber for stock rims)]

is <

[(gas mileage savings with onroad tires in miles per gallon)*(gallons used per year)*(life of Disco in years)*(optimal mileage with onroad tires in 1 gallon per miles)*(average cost of gallon of gas over life of Disco)]

Then:
it would be more cost effective to some tires for off-road only and keep you high mileage rubber on for the road.

IF tires = "suck" THEN
EXIT FUNCTION
ELSE tires = "good" THEN
QUARTER PANEL = "TRIM"
END IF

There might be some truth to Blue-G, however, we did not buy these beast to compete with Honda Insight's mpg. Although, I must point out your formula is wrong...

IF {(formula from above)x (lighter wallet)} - Good looking Disco = (money left to laundry dirty socks}

Then: It's a go

bluegil and andy

thanks for the equations. unfortunately the royal coffers are low and storage space it limited. i am not a hard core wheeler, more an expedition, fast dirt road kinda guy. wanted to put the best all terrains for the buck on the car so give it more bite on the trails, while still making it livable for the street.

the stock michelins are still showing good tread but am getting that scalloping on the inside and also they might be getting noiseier - or it's just me!

so i can only do one set and make the best out of both worlds
