Upper Control Arm Scrubbing On New 20" Tyres.. Wtf?

[Gazzilla]

Well this is starting to annoy the shit out of me.. Long story short.. I got some New Tyres Fitted to my 20" rims on R34 GT-T. previously had ghey WANLI's with puncture.. no probs. got New Kuhmo's fitted to Rims, Same size 225/35/R20.

Came home Put wheels on. went for a very short drive and noticed that the Upper control arm is scrubbing badly on top flat part of the tyre, and quite audible too.. any ideas what this is? I tried to contact the place where I purchased them but they are closed.. sadly..

fairly obvious isnt it, tyre is to big for vehicle, just because it is same size as specified doesnt mean each manufacturers tyres are identical size. think of it like shoes. size 9 in different brand can be different size.

Isn't the bigger question, why did you buy 20" rims???

What width and offset?

Even with the slight differences between the patterns, there is no way a 225/35/20 should be rubbing?

Do the wheels sit well inside the guard much?

No spacers on the hub, the wheel sits roughly half inch inside the guard. im gonna get some 10mm spacers, and see if that can correct it.

How did you go with the rims? Please tell me you weren't meaning floating spacers, if you have to use any you should use a bolt on item. I had to use them on my brothers Stagea when 20s wer fitted (it had the same issue as you have).

I ended up doing a Jesse James and getting the old grinder out. Nothing too serious, just a few mill off the upper control side arms. looks good too. gave me just over a Centimeter clearance.

I don't know why I never thought of that.

Ok...

either way if you get a 225/35/20 it should be 225mm wide, 35% of that tall and for a 20 inch rim. I can tell there may be ever so slight differences but it shouldnt be much. Maybe your 20s were second hand and the tires already worn down with the last set?

Either way i will chew my tire up before grinding away my control arms

because u didnt want to die? lol yeh, grinding the arm that connects ur wheel to ur car, that sounds smart!

I once accidentally turned my panelvan into a convertible with an angle grinder. It was good fun until I realised what I'd done.

The correct answer to this entire thread is your tyre profile is completely incorrect! Factory OD (overall diameter) is approx 634mm (225/45/17). with 225/35/20 you have increased your OD to 665mm which is close to 5% or an extra 30mm which would have most likely thrown ur speedo out as well. In QLD, the max you can increase your OD by is 15mm.

So I would advise you to go back to whichever tyre shop you got your wheels from and get them to put the correct profile tyres on. Without knowing what width your wheels are, I'd recommend 235/30/20 to bring it close to factory OD.

different tyres have bigger tread then others. with kumos mine rubs on the coilovers at the back. if you get 225/30/20 they will be exactly the same size as a 33 stocky so you should be fine. i got sunny tyres once n the 20 was smaller then my stockies standing next to it but i still got defeted because " my speedo was out". load of bullshit. it changed it by .5 km/h. moral of the story is dont get kumos...they will be balled before you finish your tank of petrol
