2020 tires

[Njgpros]

Hello I have a 2020 Trailboss with standard
Lt275/65R18 tires. I'd like to get new tires that would make my trailboss taller without any modifications. What's the biggest tire I should get and any pics out there?

For the most part, 295/70/r18 or slightly different but similar 35x11.50. There are caveats with most of these changes, especially brand and actual measurements of the tires you are looking at, closeness to upper control arm, willingness to run spacers, ect.

Be mindful of possible weird shift points and breaking feel with the taller tires. The electronins are going to be off. Im on the sideline for a tire upgrade myself until I can test 33 or 34 tires before committing.

I had the same last week 275/65R18 factory wranglers. Yesterday I installed 1.50“ RC level kit only. No wheel spacer, an installed 285/75R18 BFG HD-TERRAIN T/A KT, I have no problems on locks or reverse 34.8” tires. I love it!

I'm gonna suggest you upgrade the UCA's as well. If you don't you may regret it at a bad time.

Can you please send clearer pictures. Also you said you installed a leveling kit to the front correct? Do you know how much that as well as the new tires got you?

I have about 20K miles with 295/70s (about 34.3 in) on stock 18 wheels. There is zero of what you describe other than my speedometer is off a few MPH

Yes front only! Total $2000, these tires are expensive $1700 installed.
The leveling kit installed $300.

I was told by my trusted mechanic about this, I dont have any personal experience. He advised about the funky stuff especially in "sport" mode, when he said the shifting occurs at different RPMs. Having said that...I too probably will go with 33s very soon.

I'm sorry I didn't mean cost I was interested in how much more height difference it got you from standard

Stay away from Les Schwab whatever you do!

I went with Goodyear Wrangler Duratracs in 285/75r18. Mathematical that works out to 34.8", but Goodyear says they're actually 35.1". Slight rubbing at full lock when I first put the tires on. At the first tire rotation (5,000 miles) the rubbing disappeared. To be fair, I have performed the mud flap delete with the kit from McGaughy's. Rough Country is about half the price of McGaughy's.

Not installed yet, but I have a Readylift 2" sitting in the garage waiting to be installed.
