275/55/20 vs 285/55/20 tires

[Patrick Newman]

Anythought on which size works better also is their any issues with rub

[LongrangeLauber]

The 275 is a factory size tire, the 285 is going to be wider and taller. 285 is tread width and the 55 means 55 percent of 285mm is the sidewall height

So with that math, its only like a 5mm difference. Should be no problem.

I run a Pro Comp 295/55R20 (they call it a 33x12.5R20 but its slightly smaller) I have a slight rub on my gatorback flap at full lock when the suspension travels. I can fix it with a tie back but I rarely rub it so i havent bothered yet. My buddy runs a 305/55R20 BFG AT's with molded mud flaps and he doesn't rub at all. It all depends on your wheel offset. Both our stock 20's have a +26 and leaves me no where near my control arm or sway bar like everyone else says. You will have no issue running either of your selected tires. You will notice a decrease in power and fuel economy with a wider taller tire. My E load Pro Comps are 35lbs heavier per tire than the passenger car rated Wrangler SRA's it came with. My bud and I are both running R.L. 2 1/4" front and 3" blocks in the rear. You wont need either to clear a 285. Here is a link I used to get a rough idea: https://tiresize.com/comparison/. Note that aggressive sidewalls and raised lettering will make a tire wider than its advertised width, all tires from different brands with have differences in actual geometry.

I've got the 2.5" Ready Lift and run 275/65-20 BFG KO2's. No issues.

Be sure to look at the ACTUAL TIRE SIZE, each brand differes in actual size. I use tireracks website to see actual specs for each tire.

 

285-55-20 all the way!

Is it possible to run these size wheels and tires without a leveling kit ?

[fondupot]

I've had both. They are pretty close. The 285's are 10mm wider and about 0.4" taller. Not really a substantial increase over stock.

 

I had 285's when I had Cooper tires. But I traded the coopers for BFG's and went back to OEM 275's. I can't really tell the difference.

Yes, you can fit 285/55/20 without any suspension mods. And, in my opinion, they'll look better than the 275's.

A little wider tread impact fuel mileage negatively?

[Big Whiskey]

Going from stock 275's to a 285 or 295 all terrain won't make much difference. Running something like a 305 mud tire will be noticeable.

I'm running 295/55/R20's with 0 Offset rims. No rubbing. 2.5" Level though
