I currently have plus sized 245-40-18s on aftermarket OEM rims. Looking to buy XXR 530 18-8.75 inch rims which I am told by XXR and research have an offset of 33MM. If I keep the current tires will these rims fit or will I have to go back to stock 225 /45-18 tires? (Conti Extreme Contact DWS). These have a pretty deep concave to them and was told by XXR they should fit without fender rolling. Or should I scratch these rims altogether? Do not want to do any fender modification just to get a rim on. Thanks!

1. Wtf are aftermarket OEM wheels?
2. That wheel setup you want will fit without issues. If you want it to be concave though I'd suggest a wider option.

Thanks for the reply. 1) I should have said " aftermarket/re-production OEM STYLE" wheels. 2) sorry I haven't gotten back to you sooner, work, holidays etc.

I appreciate your getting back to me with the advice. Given the early onset of winter and snow, I'll think I 'll wait for the new wheels until spring, run the rubber I have as well through the winter too.
Once again much appreciate the info. Have a great holiday.
