What size tyres do you recommend?

[ImportR]

For 17x7.5 rims

Rota GR-A's - will go on my CTR, not lowered, yet. More thinking either 215 or 225?

cheers

personally i wouldn't go any wider then 215

in case of rubbing? or just the looks?

well a wheel with a width of 7.5" is 190mm, if you've got a tyre with a width of 225mm thats a 35mm hangover, 17.5mm each side. Lets say you go for a 45mm sidewall you've got 45mm to force the tyre back to 190mm which puts it at an angle of 68 degrees which imo isn't good for a tyre. The smaller the tyre wall the worse the angle is too.

For the standard wheels/tyres sides you're looking at an angle of 79 degrees

(the above assumes i've done the calcs right)

Good answer!

So it looks like 215 is the one to go for. Thanks for the explanation!
