To those with the Juice/Attitude and 315's

[SamPap]

I recently installed my 315/70/17's. I will probably not have the dealer calibrate my speedo and will rely on the Attitude for the accurrate speed.



My question is ... ... ... what variable do I use for the tires. The manual gives a variable for 35 inch tires but I believe these 315's ar something like 34. 9 inches.



TIA

It would be less of a hassle if you have the dealer take care of it. That should maintain the accuracy of your overhead as well. Mine did it for free, Otherwise I think he said it would be a $45 charge. We are runnning almost the identical set-up, I got everything from Rip as well.

My BFG 315s on 17/8 rims are 34. 36in diameter. This calcuates to 605rpm.



BFG Manufacturer specs shows 34. 5in and 601rpm.



I used the 605 and seems to be accurate. Either spec is going to be very close.



My dealer did it for free also in less than 5 minutes.



BTW, waiting patiently Oo. for my Juice with an Attitude.
