RE: tire size ?
ORIGINAL: dimebag
this tire **** is a headache... what DR size should i go w. then? i was thinking the 255/60/15s, but if your saying that not good... what should i go w. im either running MTs or BFGs maybe 225/50/16?
and also, stock the tire height is 60(talking about my street tires i need to buy too)... but i just read another thread about ppl using 40-45... is that a better idea? or should i stick w. xxx/60/15?
thanks for the quick help...

This is actualyl VERY incorrect. A 225/60/15 has an overall diameter of 25.6"
the "60" in your tire size is NOT 60mm. its a percentage of the tread width of the tire. in this case being 225mm
so although your math is correct, your variables are not.
225
100 = 2.25
2.25*60= 135mm
(135mm*2)*.0393701 = 10.629927
~10.6+15= 25.6"
(i used to sell tires)
*edit* changed formatting a lil bit
i figured is add this too
my rear tires are 275/40/17
275
100 = 2.75
2.75*40= 110mm
(110mm*2)*.0393701 = 8.661422
~8.6+17= 25.6"
so im even rockin the same size tires (overall)
Your new fomula should be
Section width divided by 100.
multiplied by the sidewall height number (your tires. 60. mine 40)
multiply this number by 2, then .0393701
add Rim height and you have your overall tire diameter
((((W/100)*H)*2)*.0393701)+R <--- for you math nerds!! (remember your order of operations)

hey topless, it asks for tire size, that would be including your sidewall.
Correcty me if I'm wrong guys;
Stock tires on my stock 15" wheels (87 GT) are 225/60/15
that means a 60mm sidewall.
multiply that by 2= 120 mm of sidewall.
according to my calc. that's an additional 4.72 inches.
Add 4.72 + my 15" rim and I get 19.72 total height.
To do is yourself, my calc. says the conversion factor is
1 mm= .0393701 inches
so your sidewall height, then times 2, then times .0393701.
add this to your rim size and your set.
Hope this sheds some insight.

RE: tire size ?
ok... i think i might have it... for my DRs, how about 225/50/15? seeing that the car is stock... or should i try to go wider? the BFGs only come in 225/50/15 that will fit my app. the MTs come 255/60/15, 235/60/15. so i think thats really my only 3 choices as far as DRs go.. unless im missing something...
and as for street tires... stock its 225/60/15... but again, i read another thread talking about xxx/40-45/15s... what should i do, 60? or 40-45? and as far as the 225...should i stick w. that or try to go wider?<w.out it looking retarded.

your totally not paying attention

RE: tire size ?
A 225/50 is very small, like less than 24". I wouldn't go that small. I say go with the 235/60 which is 26". And BFG does make a 235/60. The BFGs will get slightly better mileage than the MTs, but the MTs will hook slightly better at the track than the BFGs.
