Hey guys, I know it might sound weird, but I'm wondering if I can find an alternative answer to my question. I'd like to try a wider (larger than the nominal width of 275mm) on my '17 XC90 T6 Momentum, but not sure if that's even possible. TireRack offers no greater than 275mm, too. What else concerns me is the vehicle OEM fitment options and as per Wheel-Size. I see not much of a choices. All answers are greatly appreciated. Thanks.

 

you can use Tire Rack's web site to look to see which tire brands sell something wider than a 275 with a similar revs/mile - something like a 295/40-20 may be found that's close to the 275/45-20, but 295s need a 10 or 11 inch wide rim which may be a custom for the Volvo's bolt pattern. Keep in mind that the 275 is already 11 inches wide and 295s will be 2 inches wider than that. Try laying a 13 inch ruler across your current tire then turn the fronts lock to lock to guess on clearance issues. I suspect the 275s may already fill out the wheel wells to the point of rubbing on a full lock turn.

 

Knowing that most manufacturers don’t recommend going over 1-2 ” more than the original wheel size (for cars), I’m not even sure if owners manual mentions that in order for me to get the job done. Also, we know that VX90 has quite a lot space available under the arches and while bigger rims will look much nicer(I assume) filling the arches, I’m sure there has to be enough room for the suspension to work. Going over bumps, a ‘washboardy’ dirt road or potholes causes the suspension must move up and down, absorbing the impact and I’m just afraid if I get larger wheels are they going to be too big that they might hit the inside of the wheel arch. And going to the dealer is always a pain in the butt. Most of the time the sharks there don’t care about your vehicle but rip you off as much as possible. So I don't wanna even bother going to them. Any other thoughts?

 

not sure about sharks at your dealership, generally dealerships don't get involved with aftermarket configurations or specialty parts. If there's a factory wheel option for your model, they will be able to advise what size tire is appropriate per the factory standards. For doing oversized wheels/tires you are on your own and need to rely on wheel and tire vendors and peer experience.

 

Thanks Tusa
