Can I jsut check if these winter tyres will be OK for my Skoda Octavia RS 2010 (FL): http://bit.ly/oZ3cMu.

Current set of summer tyres: 225/45/17 so will be going to 205/55/16. The numbers in discussions do not mean much to me.

The siz e of rims: 6 x 16 5 x 112.00 x 57.00 ET: 50.00 5-hole steel wheel (9535) (based on Eiretyres)

You have 18" wheels on a 2010 model NOT 17"

205 55 16 is the correct size for winter alloys and tyres

Hi ChrisR,

I actually have the 17'' (this is an Irish spec car)

Hi

I got the wheels for the 2010 VRS off ebay at the beginning of the year - I think they were for VW Transporter or T4 Caddy - they were 6 x 16, PCD 5 x 112. I think they were £120 + £10 delivery. I got the tyres supplied and fitted on the loose wheels at my local kwikfit dealer for just over £60 each - Continental WinterContact 205x55x16.

You may be cheaper getting them separately as I did.

Try these - but you will need to check the sizes with the seller.

Current set of summer tyres: 225/45/17 so will be going to 205/55/16. The numbers in discussions do not mean much to me.

The siz e of rims: 6 x 16 5 x 112.00 x 57.00 ET: 50.00 5-hole steel wheel (9535) (based on Eiretyres)

My understanding is:

Tyre: 225/45/17

225 = tyre is 225mm wide at the widest point (not the width of the tread in contact with the road although it is close)

45 = sidewall height as a percentage of width (ie sidewall height = 0.45 x 225 = 101.25mm)

17 = diameter of wheel the tyre will fit (in inches).

Other tyre stuf not mentioned, eg R 91H

R = tyre construction is radial ply (as opposed to, for example, older cross ply tyres .... for those that remember them!)

91 = load index, bigger the number the greater load each tyre can handle (bigger for heavier cars)

H = speed rating, different letter relates to different speeds capable (also increases cost, so weigh up what speed you'll actually be travelling at, and this doesn't have to match what you currently have fitted, just has to be enough for the speed you're doing)

So, 205/55R16 tyres are radial construction, are 205mm wide, have a 112.75 mm sidewall (55% of 205mm), and fit on 16" wheels. What you lose on wheel diameter you gain in tyre sidewall height, as well as getting a more comfortable ride (bigger sidewall = more comfort over bumps as the tyre 'absorbs' imperfections) although you may lose some sportiness (is this important in winter though).

Wheel: 6Jx16 5 x 112 x 57 ET: 50.00

6 = width of wheel in inches (6 is winter wheel recommended width, spare might be 6.5J which means it's half an inch wider)

J = type of wheel shape/profile (J is fairly common)

16 = diameter of wheel in inches

5 = there are 5 wheel bolts required

112 = diameter of circle (AKA pitch circle diameter or PCD) drawn through the wheel bolt holes

57 = diameter of the hole in the middle of the wheel in mm

ET: 50.00 = offset, this is where the mounting face is in relation to a line drawn through the middle of the wheel in mm (when looked at from the front). Changing the offset means the wheel will go further into the wheel arch or sit more outboard; if it sits too far into the wheel arch you can get fouling of brakes etc when turning or fitting snow chains, and if it sits too far outboard you can get stability/handling issues and possible fouling of the wheel arch on full lock.

You can see there's a mix of metric and imperial sizes, but think what is above is reasonably accurate.

Happy to be corrected on any of the above, and sure someone will post a good link so you can compare sizes, as well as Skoda recommended wheel/tyre combinations.
