It was my understanding that a 33 inch tire was preaty much be the biggest tire you could get under a 4 inch suspension lift on the Comander.
I have to say those in no way look as big as the set of 35s 12.50 that i have for my CJ.
While I can get the 35s on my CJ with the curent 4 inch lift I cant drive it with them on it they rub every where. I would have t o say their would be no way 35s will fit under the xk with just a 4 inch suspension lift. Not with out rubbing and tearing them up.
I can tell you first hand experience
@Doright , that this is true.
There are some guys that have put on tires larger than 33 inches - but they either added large wheel spacers, extra spacers to their current lift, done a ridiculous amount of cutting and fab work, or they did it really half-a$$ed and have rubbing at full turn and just don't care about it.
It can be done, but I wouldn't feel very comfortable with any of those solutions, particularly adding extra spacers to an existing lift, which creates a lot of extra stress on some of your suspension parts.
That being said, why anybody would put the 4 inch Superlift and tires of that size, on a 3.7L V6 Commander is a complete mystery to me.
I owned an '08 3.7L V6 WK for almost 4 yrs prior to getting my Commander, so I'm very familiar with the power & torque that the platform produces.
Not to mention that an XK is approximately 700-800 lbs heavier than a WK, based on the curb weight & gross vehicle weight of each.
Based on my prior experience with my '08 3.7L V6 WK and the current set-up on my '08 XK, I think I'm in a pretty good position to weigh in on this with a fair amount of accuracy.
A 3.7L V6 XK with the 4 inch Superlift with 33-35 inch tires (assuming that all of that is true & accurate) would not perform, or handle well in my opinion.
I will also tell you that I'm almost certain, you can't get a 35 inch tire on our stock 17 x 7.5 inch rims, the tire would be too wide for the tire bead to seal properly.
You need rims that are at least 17 x 8 to safely fit just a 33 inch tire, if memory serves me correctly.
That said, in my opinion, there is just not enough power & torque in a 3.7L V-6, to handle that amount of lift and tires of that size & weight, with any kind of efficiency.
I think it would be significantly under-powered & the handling would be very sluggish.
Not to mention the prior owner has probably be taken years off the life expectancy of that engine & transmission, if it was driven with any kind of regularity.
