He mentioned in his post his original tire size was 255/55 R18. I too have this as my stock tire size and last time I got tires, I kept the same size 255/55 R18. 99.9% of my driving is on-road daily commute, but these tires keep that look and performance while giving it a bit more macho look.

That said, I am putting a 2" lift and will upgrade tires next go round, but that is because I am going to re-purpose the truck for kayaking and mountain biking.

 

There is no benefit to me in larger tires. I mainly drive this on road, with some light trail, beach and four wheeling.


Larger tires would do nothing for me. My spare is still 255-55-18. The tires will do everything I need them to do, they'll get decent mileage, and they will last forever. Larger tires on the 18" rims would have cost significantly more money. I love the rims, so I am keeping them. I have no plan to lift the truck, so I could only go slightly larger anyway. The tires look great, and drive even better.


What is the upside to larger tires?

 

I just thought the slightly larger would look better. Stock size on mine seem too small. I saw on here a few guys who went to 265/65 18 and they seemed to fill the wheel tub fairly well. Im goin back and forth. I do love the look of your tires.

 

255/55R18s work well if you are using it mostly for on-highway.

The question of going to larger tire depends on whether you intend to take it off-road and the type of off-road terrain. For example, do you encounter off-road terrain where you need to air-down to gain better handling or traction? If yes, the larger tires provide relatively greater ability to air down. You are also looking at relatively greater sidewall and bead protection with the larger tires.

Downside of larger tires is increased rotational weight which will affect your gas mileage.

Pics for comparison: 1st pic is 255/55R18 with no lift. 2nd is 275/65R18 KO2s with 2" lift.

 

Thanks for the pics. I am going with likely a 255/70/ R18 which is what the Wrangler JKU come stock with and owners take off to upgrade. I plan to grab a set, which I just saw is identical to the 275/65 R18. The 275 is a tad wider.

This is what 255/70R18 looks like with a 2" lift.

 

Hi Jim, roof rails are optional when new. Mine has no roof rails as I don't ever use a roof rack (too much wind resistance and noise IMO) and from previous experience the cast alu starts to corrode under the paint, plus I didn't want any holes in the roof.

 

Curious, what is your total height from floor to top of roof rail? I'm trying to measure to see if I can still fit it my garage with my truck. Also going 255/70 R18 with 2" TF lift. I think I had something like 5-7 inches of space remaining now. It will be tight. :-)

 

I definitely dig it!

 

I can't image I'd do anything off road where I'd need to air down my tires.


For serious off roading I have an F-250. which also rides on BFG KO2's.


You Rover looks fantastic in both pictures. It looks perfect with the lft and larger tires.
