Feedback - Plus Zero Tire Size for P5

Will also have mine on tomorrow. Hope I won't have any complaints.

Also, for all of you talking about "less wheel gap/more wheel gap" with 50's or 45's----you do realize the difference is only 5 mm either way, right? Not even a half inch. If you're not lowered, this WILL NOT make that big of a difference in wheel gap. If anything, the wider section width will give the perception of a "smaller" wheel gap.

195/50/16=97.5 sidewall.
205/45/16=92.5
205/50/16=102.5

In sidewall height I come up with about 4/10's of an inch difference between the 205/45's and 205/50's. Almost a half inch difference in sidewall height (not 5mm.) That's noticeable to most people.

205/45's
92.5/25.4mm=3.64in sidewall

205/50's
102.5/25.4mm=4.03in sidewall

Yes. 4/10ths between 45's and 50's IN A 205. If stock is at 195 (97.5mm), you're only gaining 5mm. If you were to go from a 205/45/16 to a 205/50/16, you would have the 4/10ths. But I thought we were talking differences over STOCK.
 
My 2 cents. i Manage a Kal-tire in saskatoon. You need to watch the amount you drop as our cars are ABS equipped. Putting on a wider tire will increase the diameter even if the side wall is the same. Also just because you drop to a 205/45r16 the diameter will be out quite a bit compared to a 195/50r16(stupidest size tire ever). My suggestion is a 205/50r16. It is only 2.3% difference in diameter, and does not affect our ABS. But whatever do as you please.
 
I'll be needing new tires this spring here (trying to go as long as possible with the OEM's).

So far the Pirelli P-Zero's and the Bridgestone Potenza G009's are what I'm looking at.

Gotcha! I understand now exactly what you were saying.

I was trying to show the disparity between the 205/45 and 205/50 sizes and how the size you pick will affect wheel-gap noticeably. Especially, since those are the sizes most people are interested in putting on their stockies :)
 
Can you explain how the larger diameter affects the ABS?

Do you think 205/50/16 will work on a +45 offset wheel with 1.4" drop?

I would assume that a larger/smaller tire would affect ABS in some fashion. It makes perfect sense to calibrate the ABS to include the wheel speed/overall circumference. Just an educated guess, maybe some else has more info?
 
Fuzion ZR1 205/60/16s on stock wheels... 73 bucks each at Tire Rack
FoshnizzzzzlE!!!

I shouldn't tell people about these... I'm afraid the price will go up.
 
Quite apart from everything else, a 205/45-16 tire requires a 7" wide wheel (minimum) for proper mounting and to insure that the handling performance of the tire is not compromised. Since the stock P5 rim is 6" wide, this is not an optimal choice.

A 205/50-16 tire can be mounted on a wheel with a width range of 5.5-7.5" so this would be the better choice on a stock P5 wheel.
 
thx for all the input

I appreciate everyone's input to the original question.

I've determined the following for my decision:

1) I like the choice of tires offered in the 205/50/16 size
2) I want a tire that are NOT directional tread design:
* Directionals: Yokos ES100, Fuzion ZRi, BF Trac T/A, etc.
* Non-directional choices: Avon M500 or Pirelli Nero Zero M&S (any others??)
The I prefer non-directional is due to saw toothing of the tires that cause increased road noise from the tire for long term ownership. The car is a daily driver and I do not track the car.

Non-directional tires allow you to rotate your tires in a manner that changes the direction of rotation (this minimizes the saw toothing and is better for overall wear of the tire). For example: one can rotate the LH side tires over the RH side.

To answer a number of posts on this thread...

Q. Will changing the tire size effect ABS?
A. My understanding is that so long as ALL four wheels/tires are identical sizes, a change from stock will not cause a problem. ABS works by detecting one or two wheels spinning slower than the rest. As an aside, many on this thread have also stated that the overall increase in diameter is *VERY* small at only 1.7%.

Q. Will mounting a 205-series tire on OE P5 6"-wide rims be a problem?
A. Tires are designed to have a fit range. All 205-series tires that I've seen include 6" in that range. A tire manufatcurer is not going to include a rim width that is *unsafe* in any manner in their recommended tire/rim specifications. Of course, I'm sure we could start an entire thread on the benefit to stability of a wider rim. But since you stated there will be no racing/autocrossing in your P5's future, there will be no problems.

Q. I'm looking for a symetrical tread pattern to facilitate a modified "X" rotation scheme for better tread life, such as the Avon Tech M500.
A. A check on Tire Rack revieled that the M500's do not have a completly symetrical tread patter. The Pirelli's do, however, so they would be my choice. Unfortunatly, no other UHP All Season tires on their site had a completly symetrical tread pattern.

Lets face it, Italian's just do some things better. In the case of Ultra High Performance All Season tires they have done it again! Buy the Pirelli's and start enjoying the nice weather.

Good Luck

To clarify, I was speaking of 205/50 series tires. As goldstar correctly stated previously, there should be no problems.

Thanks
