I can stick my hand through my alloys (aftermarket) to do it, and i can put my hand round the back and up and move them (i run 275s) so it's possible with the tyres on; however with them off is a lot easier, i think i can do them with tyres on a few minutes faster than pulling tyres off.Adjusted the front shocks, just wondering if I need to the wheels off to adjust the rears ?
