got a 150 on mine and had a 160 sqeeezed onto the 140 rim once that burned a hole in the chin guard tbh next time im geting a 140 runing a over sized tyre makes it handle diffrent and tbh makes it handle worse
Yeah true that, totally forgot you've got the RS wheels, aye i'd defo stick with the 150 on your RS rear wheel. But for people running excels i would stick to what i stated above ^
