Different Size Wheels/tires..

[ssnxp]

I heard getting different size wheels/tires from the stock size would mess with ABS and Stability Control and some anti-rollover system and other car systems.. is that true? My ride comes stock with 16" and most of the wheels I'm interested are all in 17+..

The issue with brakes and ABS is that, most of the time, when you upgrade to plus size wheels, you are increasing the rotational intertia of the wheel/tire combo. This effectively makes your brakes work harder, and also makes acceleration a bit more sluggish. Under real-world applications, however, it is rarely a concern unless you're using excessively large (19+) and heavy (28lbs+) wheels.

17's, cast or forged, will not cause any problems for you. Try to keep the OE overall wheel/tire diameter in order to keep the speedometer and tachometer accurate.

The problem occurs if you have different size wheels and tires at different locations. ABS activates if one wheel is spinning significantly faster or slower compared to all the other wheels or if the tires start locking up. If you have the same diameter tires all around, you will not have a problem.

What do you mean by OE? Sorry, noob =/ That's another concern, the unaccurate reading of the speedometer if I got different sized wheels.

Yea, that won't be a problem. I'm not gonna mess with different sized wheels in different locations, lol.

OE = original equipment

When you upsize tires, you generally increase the width and reduce the sidewall height to keep the overall diameter equal to the OE diameter.

ie: My 215/50-17 tires are about 0.1% smaller compared to 205/65-15 tires which is my OE size.
Not to insult your intelligence but: 1st number is the section width or width of the tread in millimeters; 2nd number is the profile or the sidewall height as a percent of the section width; and the 3rd number is the diameter of the wheel in inches. So 215/50-17 means a tire with a 215mm wide tread, a sidewall that is 50% of 215mm, that goes on a 17" wheel.

Yea, I'm really trying to keep the original 16" diameter but it's hard. Most of the ones im considering start at 17".

[touringcamry]

If your original tire size is 215/60-16 then you can go with 215/55-17 which means your speedometer will only change by 0.5% which won't be noticeable. At 100MPH, your speedo will be off by 0.5MPH...

You could also go with 225/50-17 tires which would be 1.1% different compared to OE size.

may be you want to consider ride confort too. the lower the profile, the harsher the ride.

Wow, there's ALOT to be learned when it comes to something that simple. I'll keep all this in mind, thanks, especially to touringcamry.
