Best tire size for 437m?

MaX PL · 03-04-2019, 05:06 PM

There was a big thread on this a while back but its now buried.

Looking to replace stock 255/275s on the 437m with new tire but not sure if I should go stock size again or something larger.

I recall reading many were going 265/285 but wondering if that's the best fitment or if larger is possible without any risk. Would 35r19 front and back be best whether I went stock or larger?

Following, Curious myself. i plan on running 265 in the front and probaby 305 or 295s in the rear.

Based on the big tire thread you guys mentioned, I just moved my 275 rears to the front and bought new 295's for the rear in preparation for a coming track weekend. I've only been driving it this way for 2 days now but it feels really good.

When my original 275's wear out on the front, I'll likely replace them with the recommended 265's from that thread as well.
