ya thanks for clarifying with me about stretch and bulge … ya my tires are pretty much square … k i kno u said not to use the calculator but i did for the hell of it … the tire size that i got the same diameter as my current tire size (205/55/R16) was 225/50/R16 … would that be ok? im going 5mm lower on the sidewall but 20 mm more on the tread width ---

Yes that would still fit on your wheels. Whether or not it will provide more grip, i do not know. IMO i think it would actually provide less grip, the bulge from the excess 20mm of width will flex and under higher speed cornering the tire will loose its shape at the contact patch between rubber and ground. But i’m no tire expert, so dont take my word for granted. ---

so im guessin best bet from what ive read is 215/55/R16 … whats the price difference between the federal 595’s n the fk452’s? the fk452’s have more grip than the federal 595s? ---

I don’t know the prices but I can definatly vouch for the Falken’s being amazing tires. I have never used tires that lasted so long and wore so evenly! Just my 2 cents 😉 ---

And if you want even more grip then the 452’s, go with the RT-615’s. I think they are about the same price but a lot more grip! ---

![http://www.roflsaurus.com/users/roast/IMG_1491.jpg](http://www.roflsaurus.com/users/roast/IMG_1491.jpg) Quickest Picture I could get, here’s my setup. 16x7 +32 6mm spacer 225/50R16 16x8 +32 245/50R16 AhamedG - the sidewall profile is a percentage calculation based on the width of the tire tread. As you increase the width and keep the same profile your tire will actually be taller. NVmySX, 87s15lt1, 245/45R16 on a 16x7 will bulge. I had the same size on my 16x8 and it was square. The old rule of thumb was for each 1" wider, reduce the sidewall by 5. Now that there are online calculators, there’s no need for this rule. This is a good tire calculator… [http://www.miata.net/garage/tirecalc.html](http://www.miata.net/garage/tirecalc.html) ---

all the calculator is for is diameter. so you don’t fuck with your vss to much. all i was saying. you guys takin this shit to another level. i’m kind alost reading some of this thread. then again im fuckin exhausted. i got 205.55r16 in rear. a 215 50 is the same diameter (height) and a bit wider. yet for a ka24e. really dude. wider would hurt you more than anything imho ---

Not much really. Your running a single cam…you’ve got no power to lose grip unless you drift intentionally. ---

Why not go a size smaller on much better tires? Why dont you get 205/55/16 FK452s? You’ll have better grip than 215/50/60 595s.
