Might be stating the obvious (to some) but something I didn't realise until I started trying to pick tyres for aftermarket wheels is that the profile figure - e.g. 40 - is 40% of the width.
So for a 255/40/17 tyre - diameter is 255mm, profile / side wall is 102mm (40% of 255), and radius is 17inches.
Learning this made it all make a lot more sense to me. I also have this graphic to refer to. Can't recall where I found it but it's now saved on my desktop!
I also wanted a chunky looking tyre with a solid side wall and after going 245(F) / 265 (R) , have since switched back to 235(F) / 255 (R) as I found the handling was noticeable more boggy and I use the car for fast road and track use. For ref, these tyres are on 18" BBS LMs.

Well i can't get insured on the 300 :cry:
just got my lic back after a lengthy ban for speeding etc (might have been an idea to try insurance first :slap:)
so sadly it looks like i'm breaking the 300 now, but i will have another prob next year once an insurance company will touch me.
gutted as i've always wanted a 300 and this is manual tt with nice rims, mynes ecu, twin stainless mongoose exhaust etc :cry:
i'll get subscribed today and get a thread started in the for sale section in a few days.
