325/65/18???Same As 315/70/17???

I belive that they are the same tires but im not sure. Plus All H1 Rims will fit 8 lug dodges. Im getting an 04 on Monday im looking to get H1 wheels and tires. Locally this guy has 18inch rims with 325/65/18 tires...are they the same as stock wheel size that will fit on Dodges? With 2inch spacer

 

Hey there,

The overall diameters are very close. 34.36 for the 315's and 34.63 for the 325's. Your overall difference is about .27 of a inch. Hope that helps a little!!

You may or may not know this, but I thought I would put it out there:

325/65R18

325 = tread width in mm

65 = sidewall height as a percentage of tread width

18 rim size (obviously)



to figure out tire height in inches:

(tread width) / 25.4 x (% sidewall height) x 2 + rim size

Hope that helps for future reference

 

You also have to remember that h1 wheels are 16.5". Also make sure that they are an older set of wheels because the newer model h1's have an automatic tire inflation system built into the wheel. They are a real pita to change tires on. Most shops wont even put tires on those wheels. Just a heads up

 

If the tires he is looking at are 325/65R18s then they sure aren't on stock H1 wheels

 

close 315 vs 325
height 34.4 vs 34.7
wider 12.1 vs 13
