Tyres 215/40/17 weird size?

[MrDeathLad]

also not that a 205 on a 7.5 wide will have very slight stretch, which will give a very small decrease in overall diameter. as opposed to the stock 215 on a 7.

I got Ku39 off Tempe Tyres (online). Can't fault them for the price. Not as sharp as the Pilot Precedas2 I had before, but the ride is much nicer (if that is a concern). For the price they are excellent. They are touted as a more luxury/performance tyre.

I got hankook v12 evo 215/40 r17 from jax tyres for $179 a few months ago.

I've got 17x7.5 rpf1's on my car so I should be sweet to run the 225. Instead of just doing the 2 tyres I've decided YOLO and just to do all 4 I think ku36's or s001 it is.. Hopefully the 225/45 fill abit of the arch gap aswell I know it's not much but it all counts.

225/45r17 - almost guaranteed to rub on the arch liners & I think you'll find they contravene the NSW guidelines

Have you plugged the before & after into a tyre size calculator?

I'd attach the one I use but the forum software doesn't allow exell spreadsheet attachments

Try this one. I've already entered the details.
