Is This true??

I'm running 195/55 on my stock rims. That is what came on the car when I bought it. There is more wear on the outside of the front tires but I think its b/c I haven't yet rotated them. I tried to do it myself but I couldn't break the lugs....I practically jumped on the crowbar and nothing happened. The tire place just told me that I'm supposed to go w/ 195/50. IS this how it works:
First number is sidewall width....higher number is taller tire. Second number is tire width.....higher number is more narrow? I'm not sure how it works.....help.
TIRE SIZE BREAKDOWN...
Ex. 205/45/16

1st number....205...Width of tire measured across the tread in MM.
2nd number...45...% of width in sidewall heighth..45% of 205mm =92.25mm tall on the sidewall heighth.
3rd number...16...size of rim this tire fits.
Lesson over
Figure out the rest.

Also, notice that when you shop for a tire, if you look at the brochure, they will have a list of features, etc. One column will be rim width that the tire will fit on. Most will have a range anywhere from 1" to 2" difference, ie. 205/50/16 will fit 6.0" to 7.0", with 6.5 being the preferred width. I've noticed this while looking around at the Yoko AVS and Toyo Proxes.

regardless of width and hieght on any type of tire, from 15 to 26 inch-hard driving means hard wear, that salesman was blowin smoke, you came to the right place for answers, and prolly got them already so why am i adding o the post?
Actually I have not git them yet, I was waiting to see all the feedback from this thread, It has all been very informative,
 
i have 205/45/16 yoko es100s

go to a good tire place and there will be no problems with that size, the footprint is bigger but the tire doesn't bulge out off the rim

Good response, ForceFed.

Davco, check out this link at tires.com; it even has a calculator to see the differences in the tire dimensions of different sizes.

I went with 205-50-16 Yokohama's on my P5 from Discount Tire. The tire calculator said that my speedo would read would be off by 1 mph (going 60, actually 61). The width is 0.39" wider, hieight is 0.39" taller and sidewall is 0.195" taller. I like the ride much better than the Dunlops in wet and dry conditions, plus it fills the wheel well better (considering I haven't put in springs and struts yet). Had to replace the stockers because of a toe-in problem I didn't recognize soon enough. If anything, have them mount one and put it on your car to see what it looks like.

Good Luck.

1st number....205...Width of tire--sidewall to sidewall, at widest point, not <i/>tread</i> width--in MM.

205/50/16s that I'm going to be using as winter tires as soon as I get some 03.5 MSP RHs and they work out well. as stated above 205/45 are going to actually be a little smaller that stocks and will hence throw your speedo off by -1~2mph (says 61 but going 59-60). of course with your speedo already off a little from the factory so it may just be a corrective measure so don't worry about that. I went with the 50 series just because of wanting to do winter-like tires and the fact that I'd rather have the odometer click over that much slower :D

45degree turn at 50...haha, u make me laugh...I take 90 degree turns at 50 (laugh)....ok, not really, lol.


I take 180degree turns (off ramp) at 60. Scares the crap out of anyone who is riding with me. I Love abusing cars. Anyway I was thinking of getting wider tires also with rims and was wondering what is the best set-up.

I have Nitto Neogen's in 205/45/16 and I haven't experienced any negative effects. The car literally sticks to the road, I love them over stocks. Also, they look better too; sleek low profile.
i love my nitto tires also they grip great(cool)

The "195" is the width of the tire in millimeters. the "50" is a percentage. In this case for a 195/50/16 tire, the tire is 195mm wide and the sidewall height is 50% of the 195mm so therefor the sidewall is approximately 97mm tall. And of course the tire is a 16in tire. If the width stays the same but the aspect ratio(the 50 in this case) changes to 55 or 60 the overall height of the tire will be changed in the direction of a taller tire. Hence if the aspect ratio is decreased and the width stays the same the tire will be shorter in height when compared to our base tire of 195/50/16. Also note that when keeping the width the same but changing the aspect ratio can and usually affects the width of the contact patch. you can end up with two tires that have the same width in mm but have different "widths". Its a science thats for sure.
 
well
i ordered the Kumho ECSTA ASX 205/45/16 from Tirerack.com 370.00 shipped to NY with road hazard protection.

getting them put on in the AM, now with the 45's i am in desperate need of lowering as there will be even more noticable gap between tire and wheel well....

consideing goldlines with stock shocks for now... is this an ok move?
 
yes, goldlines are a GREAT drop...and they have a relatively low spring rate which will help your stock struts survive pretty long compared to some stiffer springs.

yea most of the goldlines i sell go on stock shocks and i have never had a problem with them- chris
 
SidPro5 - You said the range on tires 6.0" - 7.0" was fine but I wanted to ask (everyone as well). I am looking at the Toyo Proxes 4 at 205/45R16 but the rim width range is 6.5"-7.5", is there any risk in using this on the stock rims since the wheel doesn't fall within range?

How true is this?
Does anyone have this application on their p5? (205/45/16 on stock rim?)

If so how is it riding?
Do you notice abnormal wear?
I had Ventus series model HRII's and with the 205/45/R16 YES i had some access wear. Handleing? psh No that was fine. Bu8t I did have a little bit of wear.
