Trailboss oversize tires

[Jeffery T Newell]

Anybody got pics of 285/60/20 tires on the factory 20" rims on a trail boss? Any rubbing issues ? Thanks guys

My friend just put 35x12.50R18 BFG KO2 (34.50x12.50R20) tires on her stock 18” wheels with no lift or leveling kit yet with very little to no tire rub.

thanks to everyone posting info and pics, helped me make up my mind. I'll be ordering 295/70/18 for my custom TB.

 

Seen some horror stories around the level/lifts and upper ball joints literally falling apart in no time. So, I'll let them come out with a decent kit and run this size for now.

any of you guys do a 75 profile on 18in wheel ? I like the 295/70 but was thinking about 285/75 for a little more sidewall

That's a fairly odd size tire, you will be limited to certain brands. I think that's the reason for majority of choices being 295/70.

 

I agree with you, and would prefer more sidewall too, though.

So 295 70 18's will fit on a 2020 trail boss with no rubbing at all? Not even at full lock?

what is everyone doing about the speedometer being off after getting bigger tires?  My last truck had a custom tune and I was able to re calibrate the speedometer but I am not sure it will work on the new truck.  Gonna be going with 35s most likely when the current tires wear down

65mph reading will now be 69mph actual. I guess the question is, is that of concern?

 

It's about a 6% increase.

So I installed a set of 295 70 18 falken wildpeak at3s. And at full lock they rub. Just slightly, maybe not even enough to worry about but they do rub. So everyone that says they don't, they most only drive their trucks straight. They were installed on a 2020 lt trail boss with factory lift.

Mine only slightly rub at full lock when reversing. Everything else is smooth with no rub at all. I run this setup...

Looking good! Wheels really pop with the front end! Nice truck mate

I was able to fit 295/70r18 Nitto Ridge Grapplers on the stock wheels. No rubbing what’s so over. They fit perfectly.

Is this truck leveled? Or stock up front?

Love the look and interested in swapping out the duratracs for these when I get my LTTB.  How did the bigger tire change your speedometer and mpg?

It’s off by 3 mph and I’m getting 14.7 mpg at the moment.
