Here is one way to figure metric tire size:
example a 235/75/15

conversion: 25.4mm=1in

width=235mm=9.25in
sidewall height=75% of 235....... 235(.75)=176.25mm
wheel diameter=15in
overall height=sidewall height(2) + wheel diameter
overall height=(176.25/25.4)(2) +15 = 28.88in

So a 235/75/15 is approx. 9.25 wide x 28.8 tall which is close to a 9:50 x 30

Too slow X2

get some 30x9.50's, put them on 6" or 7" white wagon wheels, and put the stock hubcaps back on them. looks like you're running a stock rim and you actually have enough rim to hold that bit wider tire.

these are 31x10.50's on 7" wagon wheels with a 3.5" lift.

What is the back spacing on those wider wheels? Still 3 1/2"?
