I'm currently looking at putting some 225/50R18 X-Ice Xi3s on my stock LGT rims. This spring/summer, I'll be looking to get some 245/40R19 Pilot Super Sports and join the 19x8.5 rim club (but haven't picked out specific rims yet). It'll be some pricey changes, but I'm hoping it's worth it with more of the wheel well filled in and top-notch rubber.
Those two tire sizes combine to have a very similar overall diameter. Only thing I haven't figured out yet is the spare tire, which also needs to go up in size.
Other than price, anyone notice any concerns with this plan?
