I just bought JDM ITR 16" wheels and wanted to know what the best tire size for them is- 215-45-16 or 205-45-16?

 

205 45 16, the 215 depending on your ride height may rub under hard cornering and u-turns.

I run 215-45ZR16 AZENIS on my 16" JDM wheels. I run stock ride height now, but when I lower it, I will run into some slight rubbing problems. This is due to AZENIS being wider than others in the same size.

Thanks,

I have 215 RE010s on my JDMs and they rub a little in the front because my ITR is lowered with Tein's. When I need new tires I am going to get 205s, so I dont need to keep the HAs at a stiff setting.

 

215/45/16 is the exact same diameter as 195/55/15...This will keep gearing the same and same speedometer reading

 

No, its not, 215-45-15 is the same as 195-55-15, but when you change to a 16" rim, you need to compensate for it, the correct rolling diameter to keep it as close to stock as possible would be 215-40-15, but you really dont want to go that wide, your tires will be hanging off the edges, you'll get a little more sidewall flex than you want...I wouldn't go any more than a 205-50-15 or a 205-45-16, it'll also insure that you dont rub if you're lowered.

Actually, diametor on 195/55-15 is23.3 with 892 revs/mi. There is no sutch thing as 215/40-15. And 215/45-16 has a diam of 23.7 with 874 revs per mi. 205/45-16 has diam 23.3 with 893 revs per mile(difference is because of rounding.) The 215 is approx. 0.5 inches wider.

 

Yeah, you're right, I think I was drinking when I ddi the math, and must have typed something wrong...dunno...my bad...

Well if you want to go wide without breaking the bank you might want to try 215/40/16 on the Falken Ziex 512's. They have reinforced sidewall to compensate the sidewall flex. They have good traction and good treadwear if you'll be using it as daily driven. They have a deal @ Tires.com. I don't know if it's a good deal but I guess it's ok.
