Hey guys, does anyone here have a set of 265/75 16s on their suburban? Is there any issue with the tire being too large with no lift? I would assume not but want to make sure first. This would be on a 92 1500 Suburban 4wd. Also, do you think this would mess with the gas mileage? Significantly or very lightly?

Thank you all.

 

I have the 265 duratracs on mine but its a newer body style 07 and its a 2500 burb. I also cranked the torsion bars to level. They rub the inner plastic fender well when cranked fully.

 

Sathoff,

Usually those tires would fit ok, but, there is always an occasional vehicle which there is an exception.
This happens most frequently, because the Mechanical Stops, which are not what I'd call a "precision" mill, vary to some degree.
One can always do a quick "spot weld" on the tip of the Stop, and create a shortened travel for either direction of the turn.
When changing Tire Size (to larger or smaller) there's always some effect. The greater the difference the greater the effect.

 

Thanks for the replies guys. LTL, did you notice any gas mileage difference when you put the 265s on? (also, very nice, expensive, looking burban you have!)

SWHouston, I'll be honest, I don't really understand what you just said lol....

 

lol you can have the vehicles turn "stops" fixed so the tires don't rub as much, and when you go changing from the normal standard you are going to have to deal with tires rubbing when you go bigger... and yes with more tire comes less MPG....

 

Just to expand on in2pro's addendum,

If you'll look on the insides of the front hubs, there are two (one each side) **** looking projections, which stops the travel of the wheel from left to right.
When installing larger tires, frequently a spot weld is placed on one or both of those *****, to limit the travel of the wheel turn, to keep it from scrubbing the fender well.

Next time you have it up in the air, turn the wheel all the way left, then, look on the inside, and rear part of the left hub. You'll see where it contacts the stop ****.
Most times, they are in a direct horizontal line with the Tie Rod.

 

Thanks for the compliment. The milage difference really wasnt noticeable going from 245's to the 265's. The 6.0. Motor has no problem spinning them. City milage is 14mpg-Hiway is 19mpg and i have gotten over 20 on a long trip which is fine by me.
