I need to know the correct tire size for my edge evo. I put in 2600 but now my speedo reading about 4 mph high. 295/70r18 trail grapplers

 

bump it up a hundred...a see where your at then...I guess you don't have the Edge book, because it has a formula in it for tire size.

 

Google the edge tire size charts and you can find it. Your gonna have to play with it a little to get it just right

 

Thanks. I don't have the book but have googled and read it. Closest I found was for 35s. I'll just have to experiment with different numbers.

 

I told you there's a formula ... it will get you within a half mph...you gotta know the exact
size of your tire...ie I have 305 which is a 33...but the tire actually measure's 33.4...you can get this info from the manufactures web site like BFG/Nitto

 

Edge has the chart in their manual, if you have it. Mine should be about 2610, but when I put it in, I was about 7 miles over too. I changed it to 2500 and I am about 2.5/3mph off using GPS.
