Merged with Official Wheel & Tire Fitment Guide for SC300/SC400

About a month ago, I almost pulled the trigger on JIC wheels. I have heard good things about the quality from RX7 guys, and they are super light with big brake clearance and a nice, race-inspired style.

The sizes you have chosen whould be perfect for an SC with that style of wheel, in my opinion. You would be flush, but not butting out VIP style. The rear would fit a 265mm wide tire and the front a 235/245mm tire.

thanks, but don't you think 265's in the rear would rather big. I want more of an aggressive fitment, so I'm not sure if they would be too big

hell no... I think 265's are too small... 275's would work on that setup with rolled fenders and a little negative camber... personally, next time I do tires, I'm gonna go with 285/30-19's... The negative camber I run will allow it with my +35 offset...

you dont need that big of a contact patch.. why waste money?

when you want a really good handling car, you are staying with street tires, and you are doing a 1JZ swap, and you are used to an AWD 500 hp car, you need that big or bigger... plus, they fit perfectly, and I don't care about the few dollar difference, so, give me a good reason not to...

if you want the stretched tire look, I suggest you find wheels with lower offsets to justify that and look correct. The true aggressive fitment often includes putting the widest tires that fit within the fender. It is just that the aggressive wheel fitment will include an offset that will only allow a stretched tire to clear.

For example, take a look at Cherplex's car (apologies for stealing the picture, but your fitment is ridiculous!):


No one would argue against this being good, agressive fitment, and there are 265mm tires are in the rear. They are as wide of a tire that would fit inside the fender, and they were thusly used. His rear wheels are 19x10.5 +26. Had he stretched a 245mm tire on the rear, people would think, "Why wouldn't he have spaced the wheels 10mm since there is a nice gap between the tire and the fender?" This would occur even though the wheel would have sat in the exact same place.

This is precisely why I suggested a 265 tire for the +30 offset. With your offest very similar to Cherplex, you should fit the 265 tire with it very close to your rolled fender just as his is. Now, if your fenders are not rolled, you will probably only be able to clear a 235-245mm tire. But, now, you are limiting yourself from looking truly aggressive in your fitment because you are costing yourself 10-15mm of fitment because of your unwillingness to acquire fender clearance.

If you want aggressive fitment with a stretched tire on an 18x9.5, say with a 225/235mm wide tire, you can run something insane like a +18, +20 offset and still get under a rolled fender.

While the 18x9.5 +30 wheel will look very flush with the fender, in my opinion, a stretched tire will give the wheel the perception of being more sunk in than it actually is. On the other hand, the widest tire that will fit inside the fender will make the entire wheel/tire assembly look more like it belongs. If you want a stretched tire on the 18x9.5 to look right, run a lower offset. If you want to run a stretched tire because your fenders are not rolled, you are preventing yourself from a truly aggressive look to begin with.

All told, that is pretty much my wheel philosophy from all that I have observed. I chose to explain myself fully since this situation allowed me to express my opinion most fully.

ps. If interested, my next wheel purchase will be 18x11 +32 with 275/35/18 tires out back and 18x10 +32 with 255/40/18 tires up front (CCW SP20). The tires will be stretched to the maximum factory standards with wide wheels, flush offsets, and plenty of meat. I sold my recently purchased 19s to save up for these, more ideal, wheels as the offsets on my 19s were not good. I jumped on a good deal instead of waiting for the right wheels and tires. In the interim, I will be sporting Supra TT Wheels since they are cost-effective, capable, and there is always a market for them should I choose to resell them.

Wow, that was a big post.

Those 265's were BFG KDW's some of the best tires and they stretch. I've now switched to 275 Dunlop Direzza's. They are actually the same width as the BFG's. The BFG KDW's sizes are usually bigger so a 265 is like a 275 etc.

you said exactly what I've always tried to tell people... thanks for that... I think I just get frustrated with people trying to run negative offsets and 205 width tires
