Its usually in the tire size....i.e. 225/60TR/15....or 225/60HR/16 and sometimes 225/60/16 95H or 225/60/16 95T
The letter is for your speed (or as I like to call it performance) rating
or on an older SSE Bonne tire sizes being 215/60/16
newer SE Bonnes used 215/65/15s and 225/60/16s
2000+ Bonnes used 225/60/16s and 235/55/17s unless its a GXP then its a 235/50/18!
I knows my tayahs.....its my bizznass
there are underratings for Z rated tires such as W and Y
W is for up to 168 mph Y is 186+ I believe......Ive got W rated tires on my Bonne...and dont see myself going anywhere near 168 mph!
