Topic: Tyres touch body arch on 17

Hi guys,

I have a RunX 140RT (kid steps), dropped with 40mm Koenic springs and using 215/40/17 tyres. I am very happy with the ride and handling. However, when the car has 4 people inside and hit gentle humps, the rear tyres touch the arch. Space between tyre and arch is about 3 fingers.

The opinions I have heard so far are:
- The drop is too low
- The tyres are too big
- I need to get new shocks/shock absorbers.

What is the real issue here and how do I fix it?

Re: Tyres touch body arch on 17

ok i have found with a 60/50 drop ... no tyre against arch on 205/55/16
same drop, tyres scrape everywhere! even without passengers  -  215/45/17

in my case it was definately the width of the tyre as the reason I put 45profile is so the total diameter of the tyre matches as closely as possible to the new set! ... hence, only the width of my tyre was more than stock.

try a 205 tyre instead bru ... it should help

Re: Tyres touch body arch on 17

problem is the offset of the rim

YES i forgot about that! ... Shot

My wheels are for Honda fitment, not sure how different they are to Toyota ...
but the offset, big drop and wider rubber all played a part in why mine are touching the arch.
