Wheel terms and perfect wheel size?
Hey guys, I'm gonna buy rims soon and I decided to buy 16 x 7.0 Rota Sub-zeros.
I found them on Modacar, for 840.00 with some Kumho tires.
Anyone know of a place with a better price? Or better yet, does anyone know of a place where I can choose different tires?
I really wanted Nitto 555R's or some Toyo T-1's.
But anyways, if I do buy some tires I'd like to know what all the terms mean. I've searched, but I couldn't find what the terms mean.
So can someone explain to me what those numbers on the side mean. I would really appreciate it. Thanks.

What kind of Kumho's are you talking about. I have the Ecsta Supra 712's and they have plenty of traction.
My tires are 215/45ZR17
215= width of tire in centimeters(edit: make that millimeters)
45= distance from inside edge of tire(outside edge of rim) to outside edge of tire
Z= speed rating(Z rated tires are the only one that have the letter there)
R17= this of course is wheel diameter.

The default tire size for the LX and DX is 185/70/14 and the default size for the EX/Si is 185/65/15.
Use the online tire calculator to see how messed up your speedometer will be after changing tire sizes....Here
I could never really imagine the first number, the overall tire size in inches, nor the 2nd number [IMG]i/expressions/face-icon-small-smile.gif[/IMG] The higher the first number, also makes the tire fatter. 205, 215, etc.... The lower the middle number, the thinner (lower-profile) the tire.
The term "plus sizing" refers to shrinking the rubber (getting a lower aspect ratio, the middle number), and increasing the amount of rim (increasing the 3rd number), to maintain an overall wheel height of stock. (To maintain a sane speedometer.)
If you care about driving normal speeds over speed bumps and stuff, and have heard of the horrors of people with 17's or 18's (with or without lowering) having to go over speedbumps at an angle or potholes bending rims, you may have thought that you should just go with 15s, or 16s, but get thinner rubber. In doing so, you really put your speedo out of whack.... Going 68km/h might end up going 60km/h, or whatever....
"Ideal" sizes, based on tire calc, besides stock, (to maintain a good speedometer), is: 195/55/R16, 205/45/R17, or 215/45/R17.
I dunno why alot of the 2k1civic.com members choose xxx/40/R17. It throws their speedometer off by as much as 5%.... I guess they prefer the look of the lower profiler tire, and are willing to sacrifice looks for error.
Me? I drive on stock 185/65/R15 tires [IMG]i/expressions/face-icon-small-smile.gif[/IMG]

I'm lookin at some 205/50/17.. mad expensive... smooth I've heard.. and unless you have a ground effect kit.... I think 17 with low profile tires look silly dropped inside such a big wheel well
Hwoody77, if you want a good price search on ebay. Search for nitto tires or toyo tires and you should get plenty to choose from. I got my 17" konig vertict knockoffs and 205-40-17 tires for 760 with shipping included. Usually the good ZR tires for a set of four will run you about 300 to 450. Better than paying 150+ for one tire.

Which model are those the "ideal" sizes for in your opinion. I found that a 205/50/16 only throws the speedometer off by 1.6%. Pretty good in my opinion. That is for the ex model.
The 2nd # is actually a percentage not an absolute amount. For example, a 205/40/17 tire has a sidewall height of 40% * 205mm = 82mm. A 235/35/17 tire has a sidewall height of 35% * 235mm = 82.25mm.
