Hi there I bought some second hand ripspeed alloys (these ones: Ripspeed 15" Ultra ) with 3 very good tyres and 1 brand new. they are all on correctly but I have two issues, one I already know the solution too 1st problem is the rear wheels rub against the arches, so I presume i just need the rear arches rolled (if not can someone please enlighten me ) and problem 2: on wet/greasy roads they handle very badly and i have encountered atleast 5 times where the car just slid forwards isntead of turning all times nearly causing bad accidents and each time going onto the other side of the road What could be causing this? they are iirc 205/45/15. in the dry they are fine and I have no issues but in the wet they are LETHAL!

Would I be better off changing back to my steelies or is this a fixable problem?

Thanks,
NERO

Sorry guys i've posted in the wrong section, could a mod/admin please move this thanks

Well for 1 the tyres are too wide that's why they are rubbing... Are your tyres on the right way around? As do the tread pattern all face the right way? And you driving like a mad man lol
