Hi guys, I've been crunching numbers and found out that my stock tire size is causing my speedometer (and odo) to be 3.8666% off and to fix it I will need 215/50R17 (stock is 215/45R17), will the 215/50 fit in my wheel well with no rub? It is at stock height and i don't plan on lowering it or anything. its not that big of a difference but i just wanna be safe
To calculate i found a nice stretch of flat highway and set my cruise to 60(according to the speedometer) then i time myself (multiple times for acuracy) on how long i travel from mile marker to mile marker (if you watch your ODO it won't work because it'll be just as off as your speedo).
for me i traveled a mile in 1:02.32 (when it should be exactly 1:00min)
so that is 3.866% slower than actual speedo reading, so to compensate i need a tire with approx 3.866% larger circumferance (215/50/17s are 3.4% larger in circumferance)
