I need help on rims sizes... anyone please help!!!!!
I have a 2000 Tiburon, and I'm trying to get some white rims and tires.
1. What size of rim and tire would fit on my car without any modifications?
2. Where can I get a good deal on rims and tires for my car?
Please let me know.
Thanks guys!!!

Input your stock tire size, and then pick the desired size, It will tell you how much it will upset your speedometer. Needless to say, play with the sizes untill you can find a combination that doesn't affect your speedo.
Usually for every inch you go up in rim size, you lower the sidewall profile by 10.
So if stock you have 195/55/R15 you would go with 195/45/R16 or 195/35/R17.
But..you can play with that a bit by going with a little wider tire, and run a 205/40/R17.
Input those numbers...and your own into that wheel calculator. I'm sure you'll find a wheel tire size you will want/like.
In regards to best deals on tires and wheels??? Theres litterally thousands of places that sell tires and wheels. Your best bet is find a style or two that you like, then call around asking for prices.
A lot of people like www.tirerack.com, but don't forget about your local tire/wheel stores. They HATE to keep stuff in inventory and may be willing to put the wheels/tires you want "on sale". I just use www.tirerack.com as a pricing guide. If the price is cheaper, I know I'm getting a good deal. If the price is higher, I know Tire rack will hook me up.

Vehicle: 2001 Tiburon
so that means I don't need to do any modifications?
I could just take my old tire and rim and put the new ones on?
And I'm getting confused with these numbers
205/40/R17?
I guess the first one is the width... and the third on the size of the rim, what's the second one?
Hey Random, did you get rims and tires for your car? Which size of rim and tire did you get?
Or what size of rim and tire would you recommend for my 2000 Tiburon white?
Should I get white, alloy, or chrome?
Please let me know...
Thanks for the info Random, I really appreciated!!!

You got the numbers right, but the terms wrong. Let's make things clear, we're talking about 2 different things. Wheels and tires.
You either pick your tires first, then pick your wheels, or you pick your wheels first, then pick your tire.
Since we don't want to fit 350 wide tires on the tibby, we are going to attack this from the TIRE side....
first number is width of the Tire...In Millimenters
The second number is the "Height" of the tire. It is a percentage of the width. a 40 tire is 40% of the width of the tire. So a 350/40/18 has a taller sidewall than a 110/70/18 tire does.
(40% of 350=140 mm High)
(70% of 110=77 mm High)
The third number is the size of rim that it will fit on. R15 fit on 15 inch wheels, R18's fit on 18 inch rims.
Your stock tire size is 195/55/R15. Go check, I'll wait......(I'm guessing here so I could be wrong).
Assuming you want to Pimp out your ride with 17 inch wheels, we need to lower the aspect percentage of the tire.
195/55/R15
205/40/R17 is the closest to stock size. It will throw off your speedo -0.03 mph at 60 mph. Not bad.
Or
205/45/R16 which will throw off your speedo +0.47 mph at 60 mph.
Now we know the TIRE size...we need to know what wheels will fit these tires.
That will come later....

Part II On to the wheels!
We now have 2 different tire choices picked out.
205/40/R17 and 205/45/R16
If you remember from above, tire with is measure in millimeters. Wheel Width is measured in inches. (Gotta love our American System!)
So...to find the right wheel, we need to find out what 205 MM translates to in inches.
205 mm translates into 8.07 inches.
As a general rule, you don't want your tire more than one inch wider than your wheel, so we can use any wheel between 7" and 8" wide.
Think we're all set? Wrong.
There are 3 wheel specific perameters we need to add into our perfect wheel solution.
The bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs. Bolt patterns can be 4, 5, 6, or 8 lug holes. A bolt circle of 4x114.3 would indicate a 4 lug pattern on a circle with a diameter of 114.3mm. This is the size that tiburons and Elantra's have.
Next is offset. This get's a tad tricky.
The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types.
Zero Offset
The hub mounting surface is even with the centerline of the wheel.
Positive
The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars.
Negative
The hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset.
If the offset of the wheel is not correct for the car, the handling can be adversely affected. When the width of the wheel changes, the offset also changes numerically. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside. The stock Tiburon offset is +42mm. The stock Rim size is 6.5"
So..we need to do math again.
6.5"= 166 MM
Centerline would be half of that.
(83 mm + 42 = 125mm)
Our stock tires mount 125 MM out of 166 or just about 5 inches out of 6.5 (75%)
So if we go with a 7.5" wheel, what offset will we need? Class? Anyone?
7.5" =190 mm
190 / 2 = 96
96 + x = 125
Can anyone solve for x here?
The answer is 30. (Wheel offsets are in increments of 2, but 28 would have also been acceptable)
If we go with a 7.5" tire with a +30 offset, you retain the stock mounting location of the tire, more or less.
Due to the fact that there is some room in the wheel wells to play around, a 40 offset 7.5 inch wheel will work. However, if you lower your ride with springs, I would stick with a +30 offset to prevent rubbing on corners and bumps.
For those of you who like graphics, and want to do their one homework, and find out where alot of this stuff comes from...

Hey, thanks so much Random...
You're a genius!!!
How do you know all this stuff?
Thanks for all your help.
I'm in the process of hooking up my car.
If you want to see a pic, let me know, and I'll post it.
And maybe you can give me some suggestions =)
Thanks again, I really appreciated.

I wanted to go a little wider, my tibby was originally 205x50x15 and went to 215x40x16 and lowered with Eiback springs and looks very nice and no rubbing. Try the numbers in the calculator but I think you would be OK. Using tire track has the advantage to show you the rims that fit the vehicle selected. Mine Masitally President 16x7.5 and yokohamas a520 215x40x16 and Eiback springs. I still feel 17 is too tall which limits width. Is just my personal taste, I preffer wider tires than taller rims.

Mario-
For every 100 Miles, you are logging 103 miles due to the smaler tires. They are also adding about 2 MPH at 60 MPH, and about 3 MPH at 100 MPH.
In the big scheme of things, not that much really. When you next get tires, try 215/45's They match the stock wheel height better than the 40's do, and you will record less mileage than you currently do.

Ok, this whole thing about wheel and tire sizes are confusing me.
Random, can you just tell me the best size of wheel and tire I should get without any modification?
So, I could just shop for that size, it'll save me alot of time =)
And should I go for a 16 or 17?
What do you think?
And I have a white 2000 tiburon... I should go with white wheels, right?
Please let me know, when you get a chance.
Thanks again.
