Tyres rubbing on suspension upright

Hi everyone,

My first post here after reading and lurking for a few years.

I have 265/70r17 tyres on 17x9 (et30) rims on my 150 series, the car also has a 2” lift.

I haven’t noticed any issues in the last 10-15k kms since they’ve been fitted but had the wheels off to do the brake pads the other day and noticed the inside of the front tyres have rubbed on the suspension upright.

Parked in the driveway there is about a 3mm gap between the tyre sidewall and the little bump on the upright. There doesn’t seem to be any play in the bearings so even though the gap is pretty small, I wouldn’t have thought there would be any movement between the parts but thought maybe at low tyre pressures and in some 4wd scenarios they might touch.

I had to put the spare on the other day too and I’ve noticed today that it had also rubbed the upright in the same spot after only driving around town so it is obviously an issue.

I have been thinking of changing the upper control arms but not sure they will make a difference for this issue. Other than changing the tyres or rims for some with less offset, can anyone point me in the direction of what I could to solve this?

Cheers

Those Et30 rims you have (whilst also being illegal - you can’t reduce track) are 5mm closer to the uprights than standard. Changing UCAs won’t help as that don’t chg the relationship between the wheel / arm
you’ll need to get different offset rims to correct it.

3mm gap? That's asking for trouble. Tyres will flex when cornering and it's not just the bottom of the tyre. The steel belts improve sideways rigidity but this results in the top moving sideways in the opposite direction to the bottom. Eg. Turning right will cause the top of the tyre to move slightly to the left.
