Default 315/35/17's do work on 9.5" rims! Measured footprint of 275 vs. 315 on 9.5" rims!

To all the people saying to me "you really need to have 10" rims minimum to run Nitto 315's" all these years, I respectfully say <img border="0" alt="[bullshit]" title="" src="graemlins/gr_bs.gif" />

I ordered 275/40/17 drag radials for the back, and Discount Tire gave me 315/35/17's on accident, and only charged me for the 275's price, so I took the 315's with a smile <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> !

I had measured my tires before, and my 275/40/17 drag radials at 25psi had a 7.6" footprint. Not bad.

However, they did look a bit more narrow than my Yokohama AVS sports up front, and they were. The Yokohamas at 35psi put down a wet footprint of 7.75"

So I try on the Nitto 315's and I will say they are not as wide as the BFG DR 315's.

They don't bulge bad at all. Yes they do bulge a bit, and looking at the tire I can see that all of the tire isn't fully utilized.

I then measured the wet footpath of the 315s @ 25psi, and it was 8.5". To my surprise they did put down a bigger footpath even on a smallish 9.5" rim.

So I'm not sure if the footpath would be even bigger with a wider wheel, but the footpath is definately .9" wider with the 315's per wheel, and they definately hookup better.

So end results for the footpaths:

Yokohama AVS Sport 275/40/17 @ 35psi= 7.75"
Nitto DR 275/40/17 @ 25psi= 7.6"
Nitto DR 315/35/17 @ 25psi= 8.5"

So I now have an extra 1.8" of total footpath between the 2 tires, even though 9 out of 10 people told me I wouldn't notice any difference with that small of a wheel.

This is good to hear Verbs, I've got a set of 315s on the way for my 17x9.5 Forgelines.

When I asked about this I was told that the tire would definitely be wider on the ground, but the center of the tire would not push on the ground as much as it should, that the outer edges would be taking most of the weight. If the center of the tire isn't being pushed into the ground because of that "buckling" effect, traction will be decreased due to lack of downforce onto the pavement.
Putting the tire on the proper rim allows the rubber to spread out nicely as it is supposed to and lets all of the rubber touch the pavement with equal pressure. No buckling.

Sounds logical.

I also don't think the nitto drs are as wide as most 315's, and are probably closer to a 295 street tire.

Put a brand new set of 275/40/17s against a brand new set of 315/35/17s on the 9.5" rims and I bet they hook about the same. But hey, the 315s look meaner! <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

I agree. Ny 315 Nittos looked narrower than my Kuhmo V700's. I always had problems with the Kuhmos rubbing the wheelwell, but the Nittos never did. You have any pics?

I would like to go with a 315/35/17 Nitto, with my factory rim widened to 17x11, but if it won't be much better than the 275 Nitto I won't hassle it.

Hey Quicken - are you still considering that guy in Monrovia, CA to widen your wheels for you? I spoke with him a couple weeks ago and he wanted to know EXACTLY how wide the tires are I'm going to be using: the NITTO DR 315/35/17. I emailed Nitto to find out but no reply <img border="0" title="" alt="[Frown]" src="gr_sad.gif" />

Does anyone here happen to know this of someone at Nitto I can email directly? I checked their website and couldn't find the info...

Thanks!

Do you have a link to the Monrovia company? It might be the same people, they have 5-6 places around the country. I'll check the site.
