what are my wheels

[bobface]

This might seem a stupid question, and even stupider because i've not posted a picture, but can somebody tell me what wheels i have?

There are undoubtedly the original S2 wheels, 5 spoke alloys. I need to figure out what new tyres to get, and what size wheel centres to get since one of mine fell off. Should i get a tape measure out?

All the information you need for the tyres are on the side wall.

You`ll see something like 205 55 15

205 is the width
55 is the wall height
and 15 is the wheel size in "

For S2s (IIRC) 205 45 R16

Tyre sizes are the most ridiculous measurements I have ever encountered.

The first number is the tread width, in millimetres.
The second is the sidewall depth, as a percentage of the tread width.
Then comes the letter R (for Rim maybe? I don't know).
The third dimension is the diameter of the rim, in INCHES?????
Then a letter representing the speed rating.

So there you go, 205/45 R16V = millimetres/percentage Rinches speed rating.

Does anybody know what lunatic decided to combine those?

It is sometimes possible to get wider tyres fitted to cars, whether on the same rims or not. You then need to match the sidewall dimension so that the overall diameter of the tyre is roughly the same as before, otherwise your speedo will be wrong.

Check out the threads on tyres because they do vary a lot. Historically, harder, longer lasting ones gave poor grip and vice versa. Tyre technology has moved on but I would normally expect grippy, hard wearing ones to be more costly.

The "R" means radial tread vs. "B" whish is bias ply. No longer used in street tires.

Another important number on ALL tires sold in the U.S.A. follow the letters DOT (Department of Transportation) inside an oval. The 4 numbers after DOT will be in another oval of the same size. They are the date of manufacture.

1st & 2nd number = production week
3rd & 4th number = production year

So 4706 means produced the 47th week of 2006. If you can find tyres more than 10 years old to buy then you are a special kind of idiot. It also lets you know if you are buying a used car with really old tyres on it.

That makes sense. bias ply are (were) called cross ply in the UK.

Nitroman your last paragraph is certainly true, we had a tyre let go on a motorway the tyre was 7 yrs old no cracks good tread, and we don't curb them either. There are a lot of low mileage Elans out there that are 17 yrs old it is worth having a look at the age of the tyres
