205/45/17 or 205/40/17 Front & 215/40/17 Rear
I have a 4 door sedan and I got 17" wheels (38 offset) - I have Tanabe NF210 Front: 1.2" & Rear: 1.6" springs installed.
I'm going with Maxxis MA-Z1 Victra tires: http://www.maxxis.com/products/autom...il.asp?id=5456 I'm trying to figure out which size of tires to go with: 205/45R17 all around or 205/40R17 Front, 215/40R17 Rear - (Black Yaris suggested this setup will give better corning) Any suggestions? |

With ET38 and NF210, you could go with 205/40's all 'round OR 205/40's up front and 215/40's rear.
I've seen this "staggered" set-up in Japan, and it looks great and works well. The difference in tire sizes front to rear is not really visually apparent, but it does compensate some for the difference in tuck front to rear, so it looks neat, even, and tight. |

I was going to do 215/45/17...... is this too big of a tire for the rim?

I am lowered with TRD springs, and my rims are currently a +42 offset.

What size tires are you running now, and how are you up front? With 205's and ET42 you should be slightly tucked by a few mm's up front? Can you confirm this? |

Personally, I'd run the same size wheel and tire front and rear on a Yaris. That way you can easily rotate the tires to increase longevity.

If you plan to race with your everyday tires then take into consideration an application that works best. If you're a fan of tire rotation (which I am not) then staggering tire sizes will prohibit rotation and decrease tire longevity some. I've seen dozen of Vitz in Japan with staggered offsets (very common application), and many with staggered tire sizes. In Japan its all about the perfect fit. For those who race their cars, they almost never use their steet wheels/tires. |

Manufacturer recommendations are generally within approximately 3% of OEM.
These are the Yaris OEM tire sizes: 175/65/14 = 23" 185/60/15 = 23.7" 195/50/16 = 23.7" (Here in the States, we commonly run 205/50/16's @ 24.1" because that's a more readily available tire size) 205/45/17 = 24.3 The difference between 14" OEM and 17" OEM is already 5.5%! As far as I know (provided there is sufficient clearance) you can "safely" vary from each OEM size listed above by approx. 3%. In Japan, I've seen Vitz (unlowered) with 205/50/17's. That's presumably within the 3% limit. It looked good, filled in the wheel gap nicely, and apparently performed well enough on the street. |

Actually, Im with 205/40/17 right now, the front is flush/looks good, but the back looks like its far in on both sides, so for future tires, Im planning on getting 215/45/17 to have a wider tire for more grip + higher profile for a more comfortable ride. Not only that, if I add Spacers in the back, the whole thing will look flush.
Also ther is a big difference in performace/comfort between 40 and 45 profile tires if you do the research. |

I ran 215/45/17 Falken 615's (which run wide) on 17x7 +38 wheels when I had my Tanabe DF210 springs and had no rubbing.
I still have these wheels and tires but I don't run them too often since my car is too low now with the coilovers, I'll probably need to go back down to a 205/40/17 to make them fit due to the taller diameter with the 45 series. With just springs it worked well though since it helps fill up the tire gap, I would do it again if you're not planning to dump the car on coilovers. |

Thanks for repeating what I said... If you enjoy replacing the front tires 400% more often than the rears, I think you probably shouldn't drive an echno box.

I don't see anything wrong with that.. just change the 2 front tires... later change the 2 rear tires. As long as you maintain your car... keep the tires inflated properly and the wheels aligned regularly, then it really doesn't cost more if you don't rotate. |

So 300% is an acceptable estimate, yet 400% is quite an exaggeration?
