im looking at buying some 949racing wheels, 15/9 by 36
i was looking at some 225/50/15 r888 .
will these tyres be wide nuff for the 9" wheel.

sander

225/50ZR15 91W (rec wheel width) 6.0-7.0-8.0

Probably too wide (that is info direct from toyo)

A 225 tire will fit very well on the 949 15x8, I have been running that exact thing for the last two years. The 9" wheel in +36 will have some clearance issues on the rear of a Civic or Integra as well.

The Hankook RS3 in 225/45-15 fits and works very well on the 15x9 6UL. Track-tested as faster than on the 15x8. I can't see why a 225/50-15 in any tire would be any worse, especially since you have even more sidewall flex to work around.

As for fitment on a particular vehicle, that depends on the vehicle. What's this going on?

Can you post that data Andy? I'm interested in seeing it, and I've had a few requests for similar data.

.:Made in OC:.

Definitely interested in this as well.

You could run a 275 Hoosier on a 15x9 wheel if you wanted, but you would definitely be looking at making some modifications to the fenders:

What kind of 225 tire was that, Adam?

Stinkycheezmonky

Hey, it said 225 on the sidewall!

pleej

the cars a eg with a k20a2, i was looking for 235's but i cant seam to find any .
im not botherd if i have to run fender flares realy.
the reason i was looking at 9" with wide tyres were my budy has a k20 teg with 215s on 8" wheels , he tryed some 9" wheels and said it did feal better with wider wheels and tyres.

powerneedy

if you talk to the 949 guys they tell you that the 9 wide wheel with the toyo r888 225/45 or 50 are the way to go. i have the 8s right now and i know for sure i could move to the 9 and make the tire have a very slight stretch to it.

Thanks for the info

This is where my info comes from. Emilio says the 9 is worth a second a lapover the 8. Mostly in corner entry. Also allows slightly lower air pressure for better surface compliance.

I do not yet have personal experience with the 9 other than test-fitting, but I have 'em on the way.

To the OP: the 9 may need a bit of spacer on the front to stay off of the knuckle. It needs 3mm on an EF. In the rear on an EF, even the 8 will rub the tire on the trailing arm. A 9 would be much worse. But again, that's an EF. You should try a test-fit before purchase, if at all possible. Maybe your friend with the teg? Even if he only has 8's, you can fit those and look for at least another half inch of clearance in each direction.

I can guarantee on an EG Civic and a DC Integra the 8" will rub the trailing arm and rear upper control arm a bit. I actually had to clearance the UCA to prevent contact. A 9" would be all up on that.

Hankook does not recommend using that tire on wheels wider than 15x8.5.

Tire manufacturers sometimes have different recommendations for the same treadwidth in different aspect ratios. For example, Toyo approves the R888 in 225/45-15 for rim widths of 7.0-8.5 inches, whereas they approve 225/50-15 for rims 6.0-8.0 inches wide. They develop their rim width specs based on their engineering analysis of the tire, with a particular emphasis on the stresses and heat that build up in the sidewall when rims are excessively wide or narrow.

There are also some instances in which one tire is approved for a given rim width, while another tire with the same nominal size is not approved for that rim width. I can only guess, but one of the reasons for this is that actual size can vary among different tires that are labeled as the same size. Another may be that they take different usages into account; for example, track tires may be analyzed based on higher operating temperatures (both ambient and internal) than all-season tires.

...depending on offset, of course.

Not trying to be rude I just have them and with my setup dc2 chassis 949 8" 225/45/15 R888 I don't rub any where i still have my fender liners in. I have ran them from -1.5 to -3.5 camber and still no rubbing but keep in mind I do run 16kf/14kr spring rates. With 9's you better be ready to roll and pull the fenders quite a bit or flares and also either run a spacer for the rear trailing arm or grind it and weld.

nsxtasy

What kind of DC2 Integra do you have? IOW, GS-R or Type R?

powerneedy

GS-R... 949 does not make any thing in 5x114.3. sorry noob moment IOW???

let's see some pictures !!!

Interesting. I have had mine on an Integra ('01 LS) and it had the same issues as my Civic (which has GSR trailing arms). I don't know how you managed that without rolling the fenders, even if it didn't rub on the inside.

And Ken, the 949s are only available in specific offsets, so you're right, it does depend, but in this case the offset makes that happen

I have a set of 15x8 +40mm offset 949's.....with 225/45R15 R6's and 5mm spacer they get a little shiny on the inside when loaded in left handers. The Gen II 15x8 are +36mm offset, using a 5mm spacer, would keep me off the trailing arm on my Teg. 15x9's with 225/45R15's are perfect, but I would need a 10 or 15mm spacer, at least and some some fender mods to make it work trouble free.

dtcevo

I run 15x8 36mm 949 also with 205/50-15 BFG R1. EG with SI trailing arms. No rubbing, No rolled fenders. More then average camber though

thats wierd how some do rub and some dont lol
i was going to ask the tea father ,he runs 16/9 on his eg

And what racers do and make work, does not always correspond to the manufacturer's recommendations. The latter has to allow for large safety margins and a wide range of applications, while the racer/enthusiast cares about one thing: going faster in his car, in his situation. So racers often will "over tire" or "under tire" a rim, depending on rules and actual performance data.

If the safety card is to be played, then one needs to look at all of the other typical enthusiast mods that are beng made by H-T'ers like out-of-spec alignment, lowered ride heights, etc., all of which compromise the designed-in safety of the car (bumper heights, anyone?). Liability being what it is in this country, you'll never get tacit approval for that sort of thing from a manufacturer.

That said, if you do use a tire/rim combination that falls outside of the manufacturer's recommendations, you need to do so with eyes wide open and know that you do take some risk, and can't be blaming the tire-maker for anything that goes wrong.

With a 205 that should be the case

I'm curious though, no one else has had clearance issues with the rear UCA? I don't know why I'd be the only one...
