2021 Trail model CC largest stock tire size

Have not found an answer to this specific model bc I can’t tell if mine is TRD or not. Some paperwork says it is and some doesn’t mention it.
Stock black wheels and 275 65 R18 tires.
I want to go with 275 70 R18 10 ply mud tires: same width but a good bit taller. Will they fit with no modifications or do I need to drop back to 285 65 R18: wider and only a little taller.

Truck is 100% stock.
thanks!

 

Being your truck is 100% stock, search the threads on stock truck size sizes.
Being a Trail Model wouldn't make any difference.
The only difference in the TRD offroad is the shocks, not anything else in the suspension like height or tire clearance...

I bought my truck used (stock suspension) with 275 70 R18 KO2's no issues.

 

Looks like I’m go to order some 275 70 18 mud tires and just hope for the best. Seems like most can squeeze them on a stock truck.

 

I am running 265/70-18 on stock suspension and seems like there is plenty of room. Should've gone one size bigger.

Your answer should be in the beginning of this thread.

 

Well I bought the 275 70-18 and they fit perfectly. No rubbing and the truck seems like this size should have been sta dare from the factory. Handles and drives much better.
