hello, will a 245/40/18 be an acceptable replacement for a 255/35/18 tyre please? Need to order some winters and this is about the closest I can find in the vredestein wintrac make. Not looking at changing the wheels.

Yes that's fine

At 60mph your speedo will read 57 mph a difference in diameter of 1.24"

many thanks for the prompt replies. There was a calculator on this site I recall for just this exercise. Will have to take the 30mph speed traps at 25mph, winters should help if we have a cold snap.

Under the wheel and tyre section, I know it messes with the mind

he was going from a 255 x 35 not a 235 x 35, so the difference is even less!

yep, I am going from 255/35/18's 245/40/18 on the rears of an E90330D. So for the calculator I keep the wheels and offset as 8.5J for both lines of the calculation.
Thanks

I've gone for 235/40/18 winters all round. Partly as I think a slight drop in the rear size will help in the snow.
