Will 18x7.5 with 215/35/18 tyres fit on a mk3 astra comfortably? they are et45.

i know if they were 18x7, they would be no probs, but am a little concerned that they 7.5j wide.

any benefits or non-benefits to the wider wheels?

cars lowered 40mm

No gains from them the slightly wider alloy. They tyre sits better on a 7J rim.
On the 7J rim the tyre sits flush but on a 7 1/2J rim the tyre is slightly narrower than than the rim.

No idea about the fitting on the Astra though

like we tried to work out yesterday....

on my 7x 18" et49, i have 'just over an inch' of gap to the inner arch

now if you have 7.5x 18, thats an 'half inch more' out, and with et45 thats 4mm more sticking out...

therefore your will stick out 0.5 inch + 4mm more than mine

and thats not even an inch... therefore - you still have plenty a room to avoid problems :)

with the offset being higher than 42 still - you will not experience tramlining!

Im Sorry. I totally disagree with everything you've said Olly.

EVERY mk3 astra varies in some small way. Ive seen cars have 18s on with no arch mods and still carry three up.

Ive seen astras need the full arch lip cutting off even with no rear passengers.

its totally car specific. My bet is, some of the arch WILL have to be trimmed.

Fair play :beer:

Maybe I am wrong lmao

Not sure just how much they vary tho...

Like I said earlier - Bren has 7.5x 18s with et45...

Has he done his arches? if so, was it because he wanted to - or needed to?
