Ideally I don’t even want to change rims and just upsize to wider 15” tyres but I am not sure how much thicker can the alza advance stock rims accommodate. Are those tyre size for 15inch common? Just worried there are not much choices for the 15 inch... and ideally, if you are changing rims, you’d wanna upsize too.
the stock alza 15" wheel is narrower than most normal 15" wheel in the market..
(6jj for alza instead of usual 6.5jj and 7jj for performance wheel design)
so 185 width is already max perfect fitment for stock alza 6jj wheel
195 width goes to usual 6.5jj wheel
195 or 205 width for 7jj performance design wheel...
good thing is... performance TYRE is plenty available in 195 and 205 width format for 15" size...plenty and quite affordable too
