I've seen idiots squeeze 44s on 7" wheels before. Bottom line is, if you wanna be stupid....the door's open. LOL

 

haha

i like the stock rims too, how would 305/70/17 do on the trails???........2" wheel spacers????
om my stocky ride??? or 285 with no spacers, or 1.5" with ?????

2" is 50mm
1.5" is 40mm
1" is 25mm
3/4" is 20mm

tires confuse me

 

I have 315 70 17 on stock wheels with 1.25 spacers... you need spacers on 285 as wheel (they will rub your sway bar if not)

The big think you need to know.... 35/12.50/70 is the same height as 315/70/17... but the 315/17/70 is only 12 inches wide.... works much better with stock wheels...

 

nice pics...
so whats your lift? 2.5"?

305 would be 11.5's then......im only on HD stock susp....

 

thanks... its a rough country 3.5 lift....plus 2 inch pucks up front to level out the dumb rake put into 08's plus the weight of the winch... not sure on 305's.. I know the 285/70/17 are 11.25 i think.... btw....got a barely used set for sell!!

 

Just FYI...

The first number in your example (305) is the width of the tire, in millimeters. A 305 tire would be 12 inches wide.

The second number (70) is the ratio of height to width.

To get the actual diameter in inches, first convert the width to inches by dividing by 25.4 (1 in = 25.4 mm):

305/25.4 = 12.0 inches

Next, multiply that result by the ratio, 0.70, to get the tire section height:

12.01 * 0.70 = 8.4 inches

This number needs to be doubled because it only accounts for half the tire:

8.41 x 2 = 16.8 inches

The actual diameter of the tire is this number plus the diameter of the wheel:

16.82 + 17 = 33.8 inches

This does not take load into consideration.

 

285 wide is 11.5, 295 is 11.7, 305 is 12, 315 is about 12.5-12.7...

315 seems to be a little smaller than a 35 but wider.

 

are you running wheel spacers??? if so how much?
thanks

 

thanks for the diagram
very helpful in clearing this up......

 

im also running 37 on the stock moab wheels with some spidertrax spacers.
