Toyo T1R speed rating?
Just a quick one, my new tyres arrived today. The size is 215 40 zr 17 w87. In the 'old' days zr was up to 149mph, I have been told now that the w87 is the new load/speed index and they are safe to 168mph and the zr is irrelevant. Is this correct?
Thanks, Martin.

Thank you for your reply BOB'5, very useful. Just out of curiosity does anyone know what the zr does relate to? My current tyres are just r and my previous Primacy's are also r.

Ok, i've done a little research and now know what the zr refers to! R is for radial and the z is for a tyre with a 149+ mph rating. The w was added as a maximum for the the unlimited 149+ rating. You never know someone may find this of interest
