I have done some searching but i am still a little confused. I would like to know what tire i should choose for ronjon inspyre 19 x 7.5. according to Dan Martin's master guide a 235/35/19 would have a 0% difference from stock. However what is the difference between that and a 225/35/19 or a 225/40/19? Maybe its just preference?

Thanks!

All the answers you'll need.

VS the 235/25-19:

225/35-19 will read 1.1% too fast. (travelling slower than indicated)
225/40-19 will read 2.4% too slow. (travelling faster than indicated).

If you had to choose, I'd go with the 225/35-19.

 

Thanks a ton!!
