This is for a 240SX, not any Honda, just to be clear. I'm trying to decide on what tire to throw on the new wheels, and I love my Azenis, but 215/45 is the only size available for 16" wheels. While optimally they would be mounted on a 7" wide wheel, would there be any downsides/problems on a 7.5" wheel? I'd imagine not, but just looking for opinions. This will be for street/autox/HPDE duty, with compromises being made for street use if it's an issue.

 

I would rather mount them on a 7.5" wheel then a 7" wheel. You shouldn't have any problems.

 

I've seen those tires on a 8" rim before. Wider = better, without question.

 

Excellent, thanks fellas. Mods, feel free to delete if you'd like, my question has been answered.

 

for reinforcement, i had 225's on my 7.5'' wide wheels on my old 98 240. the tire was a hair too large for the 225's, so 215's should be perfect.

 

here's the 205/50-15 on an 8" wheel... they run pretty wide!

 

I've always thought that the 215 45 16 azenis fits like a glove on the 7" wheel but I've never seen the 215/45/16 on a 7.5 so I could be wrong.

 

Thanks again all, and Tnord, I appreciate the Nissan-specific outlook, it's surprising how dumb most of the Nissan boards are with respect to track questions.

 

weve run these on 240SX also on 7.5" wide wheel with no sign of stetching. Look and perform great.

There are two 16" size Azenis Sports, 205/55-16 and 215/45-16... I'm currently running the Kumho MX's in 225/50-16 and they fit perfectly on 16x7.5 Kosei K-1's, so I'd imagine the 215/45-16 Azenis Sports would fit the K-1's perfectly too. I also have the 205/55-16 Azenis Sports mounted on 16x7 enkei RS-5 wheels, and that fit is about perfect too.

 

The only thing to watch out for is 215/45x16" is not a normal size. It may change your gearing on your car. Could be better or could make your car slower and throw off your speedo and odometer.

I had the 215/45x16" on my 16x7.5" Kosei K1s at the end of 2001. My car accelerated like a pig and the tires were so wide that they rubbed all the time. The width of the tires are more like 225 or 235.

 

sort of off topic but why are the azenis offered in such low variety as well as awkward sizes? i don't know anyone who would put these tires to use on a 225/45/17 tire..maybe 225/40 or 25/45 but it doesn't make sense i need 215/45/17 azenis

feel free to ask me any nissan-specific question. i've had a few of them over the years, and spent lots of time on track with the 240. and yes, the nissan boards are wastes of time (ie Zilvia) when it comes to track stuff.

I was about to say that - they're 23.5" tall, really almost an inch and a half shorter than a 240SX should really run. IMO the 240SX gearing is already a bit short considering the low redline and prodigious off-idle torque. Making the gearing another 6% shorter really isn't going to help.

Considering how much taller it is, the 205/55-16 probably gives up nothing in the way of contact patch. It's an OEM 240SX tire size.

 

adam, if anything you don't want them to be too wide as they'll flex more, if that's possible w/ the azenis sports. Strech is better if possible, just a little, it'll triangulate the force a bit better providing for a bit more predictability as you don't have to worry about the tire flexing

As far as gearing is concerned, I'm actually not sure how the gears will be spaced, as the engine will be the overplayed SR20DET . And by my calculations, which could very well be incorrect, I have a 0.7" difference in overall diameters. And Matt, what are you doing on here, get back over to DGTrials . Oh, and Tnord, I just might be hitting you up later once we get the car running, so thanks for the offer to help

SR20DET gearing = KA24 gearing. Transmission ratios are the same and they both had the 4.083:1 final drive from the factory. The SR has a 7700rpm rev limiter though - it makes much better use of it.

They're only 0.7" shorter than the 195/60-15, but that was the shortest tire ever used on an S13 or S14 worldwide. 205/60-15 is also a stock size, as well as 205/55-16, which are 1.2" and 1.4" larger, respectively. I ran 205/60-15 on my 240SX.

 

hey ssca guy, run the 7.5 i have them on 16x8's, and the wheels is a tad wide, a 7.5 would be a better fitment.

tough pic to see, but here they are on the 'ubercivic

 

Thanks, Rodney. Any luck selling those axles by the way?

And AKADriver, are the actual transmissions the same, or just the gearing?

 

The bellhousings are different to fit the different bolt pattern on the back of the SR block, but the internals and rear housings are the same.

 

looks great rodney!

 

I run them on 16x7.5 rims, and they fit perfect. With the right amount of neg chamber they wear real even with track use.

 

hey, where are you guys all finding these 16x7.5" wheels?

I want some 16x7.5" wheels

 

Kosei K1s, from tirerack.

 

nope, not in the 4x114.3mm bolt pattern
