Hi I currently have 20” rims with 245/35r20 tyres I was going to change to 19” rims 8.5j 8j with yr falken 435s tyres being 245/35r19 my question is that because of the reduction of rim size should I go with a tyre with more of a side wall and if so what would you guys recommend? I don’t want too big a gap around the wheel arch. The falken tyres are the same profile as the ones I have on, only different diameter. Thanks for any advice!!
