When changing to 37's

[Aramco Raptor]

Hi All,

Quick question maybe someone can give some input on...

I am considering switching to 37's for summer...does anything need to be "re-calibrated" due to the larger diameter / circumference?

Will the speedo be off...if so...by how much?

Just wanna know what I'm in for.

Thanks in advance.

All depends on which 37...not all 37s are equal. I went with the BFG AT 37x12.50x17 and havent been happier. Ride, performance is still great, and the speedo is spot on now, vs being a little behind.

Do your research on 37s, weight, actual size, compound...

There are a couple threads about going 37s...some modifications are needed.

I've read about doing the pinch-weld mods and was more concerned with the speedo / electronics side.

I'm still looking at tires for now.

Thanks!

Tune it and you can recalibrate.
