Looking to buy some winter tyres for my 17" BMW 383M wheels. I believe the front wheels are 7.5" and rear wheels are 8". Thinking of buying the same size tyres so the tyres could be rotated on the wheels if needed. If so, what dimensions should I go for?

The summer tyres on the wheels now are front 225x45 and rear 245x40. Cheers!

One for Marco perhaps, or anyone else that might know.

I’ve got some 8.5” wheels for mine but have just seen some I like in the following size for sale...

18x9 et45 w/ 255/35 square

Any hope?

I’ve got coilovers with camber plates and intend to set it to about -2.5* front -2* rear.

You're going to struggle with the fronts on those.

9" is very wide front wheel and will definitely rub on the shock absorbers at ET45, you'd need a 10mm Spacer to fit them, maybe thicker.

Thanks for such a quick reply! Would be too much trouble to accommodate then, I’ll stick to the original plan and save myself a few quid! :)

I am going 18x8 et40 shortly, how is the fit at the front with the 245 tyres, is the steering any different?

Afternoon

Just about to order some 18x8 autec wizards from germany.

What is the correct et for perfect fitment?

Will be swapping the stock size tyres over from original wheels, but i don't want a stretched tyre look on the fronts. How stretched will a 225/40 look on 8j?

Car is 63 plate f21 m135i with adaptive, lowered on eibach pros

any help appreciated

ET38 - ET42 roughly. Mine are 8" ET40.

225/40 will look a tiny bit stretched on the front, but you can swap them for 245/35/18 when they wear out, which gives reduced understeer and less melting. :)

Thanks for the quick reply, looks like the options are et35 and et45, can’t see et40.

ET45 will look like an OEM fit, ET35 would look quite pokey but still miss the arches.
