15x7.5 ET35 with 205/50 too wide?

January 22, 2026, 09:54:00 PM

Hey guys! I did some research and from what I've gathered even 15x7 ET35 might cause rubbing (ofc largely dependent on ride height).

For those who have messed around a bit, would you say 15x7.5 ET35 and lowered 30-40mm cause rubbing or any kind of interference on bumps or harsh road? What would you personally recommend? I would prefer to not have to cut or hammer the **** out of my wheel arches.

Thanks in advance!

I've run ATS cups 7x15 with an ET28 and 195/50 tyres, they rubbed slightly on the back, yours will be 7mm further in so I reckon they will be ok, if you went with 195/45.

Hey! I’ve experimented with similar specifications before, so I’ll share what I’ve learnt through trial and error.
A 15x7 ET35 is usually fine for many setups, but if you go for a 7.5-inch width with the same ET and drop it by 30–40 mm, you're definitely pushing the limits. The extra half inch pushes the outer lip a few millimetres further out, and with ET35 it can sit pretty flush, depending on the car. You might be OK on smooth roads, but rubbing on the fender liner or arch edge is very possible on big compressions, with passengers in the back or on uneven bumps.

A lot also depends on tyre size. A slightly stretched tyre can help. A taller tyre profile will make it worse. If you really don't want to roll or pull the arches, I'd personally play it safe and either stick to 7J ET35 or go for 7.5J with a slightly higher offset (ET38–40). This might not look quite as aggressive, but it will keep your arches intact and prevent that annoying rubbing sound when you hit a dip.
