Rim Sizes

[Brightonuk]

Sorry for what is going to be a DHU question,.... I am running 13" rims with Hoosier slicks 20.5 X 7.0 x 13 front and 22.0 X 8.0 X 13 on the rear

I need a second set of tires (wet) I am having trouble finding 4 bolt 13" rims in the US that will work

15" rims offer more options but how do I raise the rear and front cycle wings to accommodate a bigger rim/tire combo as now my cycle wings are only a few cm from the tire.

Do I just need to run a low profile tire?

Thanks

Thanks unfortunately my only two choices are the ones above 5.5 is the widest I can get.

I am back in the UK in August but I want to bring back soooo much stuff from Caterham 4 rims aint gonna fit + the wife might get suspicious on how much money I am actually spending on this car.

I think these rims translate into........ a little more attention to the handling
