OK, following on from this, why would I need a tyre rated as ZR on a diesel MGZT? Ron's box is good, but not quite that good!

45 = Aspect ratio (sidewall) % of tyre width eg 45% of 225 R = Radial construction 17 = wheel dia index 17 (17") 94 = Load index of the tyre (670kgs) Y = speed rating (upto 187mph) Ha Ha Ha XL = designated extra load tyre The size data must be the same but you could use the tyre designated speed of V= 150mph,W=169mph or ZR= over150mph. Tyres these days are anything but simple.

Probably the best size tyres a 75 Zt can have in terms of road holding verses road noise IMO.

I’m looking into sourcing some new boots for my 04 facelift 75, the tyres I have on at the moment are 225/45 ZR 17, but on a previous post it says they should be 18’s and when my Speedo reads 70MPH my sat nave reads 67MPH.
Have I got the wrong wheels fitted? |
