I have an 04 1500 and it came factory 265/70/17 tires. If it has 20'' wheels it's P275/55R20 as standard, and P275/60R20 as the optional.
The size of Chevy Avalanche wheels is around P275/55R20 111S, if you buy it from 2006. If you on the other hand, want a tire from before 2006, the size will be diffrent.
P265/65R18 (Standard) P275/65R18 (Option 1) P275/55R20 (Option 2)
It is 275mm wide
Yes, you can.
Yes they will. I put them on yesterday and i noticed it has way more grip then the smaller tires (of course). There's no rubbing or nothing its just better in the snow and rain. P275 R70 on the front and P275 R75 on the back. I recommend everyone that drives a 2 wheel drive ford ranger do this.
Yes it will because the wheel is big enough
it doesnt fit on any specific vehicle. The tires are for specific rims.
No, is the answer based on the information you provided. I really need to know the full size of both sets of tires.
No
The recommended pressure is listed on the sticker on the drivers door jamb.
p275-16s are near the limit. You'll have to gear down your front and rear diff, otherwise the big tires will bog you down on the highway.
