Why is there SOOO much difference bteween the advertised tread width between these two drag radials? The tread width is nearly the same ... 10.3" vs. 10.0".

That might be a missprint or something. I've had the 325's, and I promise, the contact area is about 3 inches wider than a 275!
LoL, Just noticed you were talking about M&H 325's, not MT 325's. Yeh, the M&H's are small as f*ck!

 

because u r comparing a m and h vs a m/t. the m/t's are severely larger.

 

That's like a 28x11 vs a 26xwhatever... tires are not very similar.

 

I think what he is getting at is the listed tread size. I have often wondered that also.

Technically if it were true MM measurements it should be:

275mm=10.8267" or American units would round it to 11"
325mm=12.7952" or American units would round it to 13"

I really don't understand how there is so much of a difference in tire brands. Units of measurement are just that. No particular tire company can change that. Kinda like how a 275 Nitto compares to a 275 M/T.

you would think a 275 would be the same friggin width no matter what brand it was.

 

Well, since the 295/45R17 MT's are still on national backorder, I was looking at putting a M&H Racemaster tire on the car in their 315 width. The M&H 315 looks like it would fit about the same as the MT DR in a 275/4R/17 width does ... on my 9.5" speedlines ... safely.

 

Since they're both about the same tread width though the advertised size is waaaay off ... anybody see a reason not to buy these and put them on the car.?

 

hmm..

ET Street says:
275/50R15 which is equivalent to 26 X 11.50R15 with a sidewall width of 11.3 and a treadwidth of 10.5

M&H says:
325/50R15 is equivalent to 10.5/28.0R15 with sidewall width of 12.3 and treadwidth of 10.3

But how does M&H rate their 50 series tire as 28''? And how does everything come up so different? M/Ts are 11.5 wide, but have a sidewall width of 11.3, but M&H are 12.3 and are 10.5'' wide??

 

the 325/50 are nearly 28" tall if not taller. dont put those on unless you are geared for it. they will kill your et.

 

But in my OP, I was comparing a MT DR in a 275/40R/17 width, which is only 10.0" tread width.
Too bad tire manufacturers aren't held to a national standard for sizes.


Agree'd ... 26" is about right for my A4 w/3.73's.
