R33 Stock Tire Size

[MFC05]

I was wondering what was the stock tire size on a R33, is it 205/55/R16 I just want to confirm this.

Also are there any differnces in the stock wheel tire size between the S1 & S2.

Thanks everyone

There's actually 2 tyre sizes for the stock rims.

1: 205/55/R16

2: 225/50/R16

If you look inside the driverside door arch of a R33 there should be a sticker with this info on it.

The stock rims for S1 & S2 were both the same, so there is no difference.

Hope that helps you.

Cheers

So your saying both of these size would fit the R33 stock rims ??

Thanks

both will fit, im fairly sure from factory they had 205/55

225/50 is the same rolling diameter, off by 0.1% or something but the tyre is too wide for the rim, its sloppy.

I thought it came with 205 on the front and 225 on the rear from factory. Ive got 225 all round on mine, fits fine on the rims. Apparently the recommended rim width for 225 is 7inch so 6.5 inch is fine

I'm not having a go at you but a profile of 50 would be 10mm smaller diameter than a 55 profile on the same sized rim, so how could they be the same rolling Diameter?

Im not 100% sure but i think this is how it works-

205*0.55=112.75mm

225*0.50=112.5mm

So the difference in rolling diameter is only 0.5mm, practically the same.

^^^yep, spot on

the profile is a ratio of the width, so going wider and keeping same profile has a taller wall

AH so that is why. Thanks for that.

ricsvtr is spot on. and yes both sizes will fit on the rims. i have a set of wheels with 225's and another set with 205's. both handle the same but the 225's suffer a bit more from inside scrubing due to the camber.

I wouldnk't run more than 205 on a 6.5 inch wheel. Wider is not better.

it' sjust not wide enough for the 225 tyre. 225 fits perfectly on an 8" wheel.

6.5 inch is fine for 225. The recommended width for 225 is 7 inch, this is coming from the tyre manufacturers themselves (Goodyear) and 6.5inch is within the range that they state. You know that 225's came on the stock 6.5inch rim from factory right? Also if you look up on Google about tyre and wheel widths there are some websites which tell you how to calculate the correct widths.
