My new 245 doesn’t have a spare wheel so I’m going to try and source one, is there a certain size that I need to clear the brakes?

 

I’ve seen a 16” steel one but wondered if I need the skinny spacesaver which is 18”?

 

Thanks all..

Really doubt 16" will clear. 17" possibly. I've got the 18" kit to be safe (and OCD)

Check the diameter of the front discs. 312mm diameter front discs need at least 16" wheels, 340mm front discs need at least 340mm front discs. I suspect the 245HP model uses 340mm front discs and would therefore need 17" wheels to clear the front brake calipers.

 

You could use the cardboard from a breakfast cereal packet to make a front brake disc diameter checker. Try making a 340mm version first and see if that's a close fit over the front brake discs with the front wheel off.

 

Some people use an old wire coat hanger to make the tool.

 

You can get an Alcar 9021 steel rim 6.5Jx17 ET38 from the Skoda Kodiaq that could be used as a spare with a 205/50R17 tyre.

 

mytyres.co.uk list this rim for £43.40

 

mytyres have a habit of including a tyre with the rim. Their website only lets you choose a steel rim without a tyre if you go straight to the Skoda Kodiaq steel rims after first opening the mytyres website. Close the window and start again if it doesn't let you select the steel rim without a tyre. mytyres don't show you that it's an Alcar 9021 just that it's an Alcar.

 

Alcar 9021 is also shown on oponeo.co.uk but its more expensive than mytyres.

As you can see from the photo of the Alcar 9021 on oponeo, it's a 20-hole design. This steel rim is an exact copy of the Skoda Kodiaq OEM steel rim. Alcar are made in Switerland so are similar quality to OEM.

 

This shows a 340mm front brake disc. This is the biggest diameter that is fitted to the Skoda Octavia MK3.

Škoda included spare wheel for my car, 340mm brakes.

 

I can go outside of office and check?

 

 

If you are after a 'full size' wheel instead of the 18" skinny space saver, then the 17" wheel from a mk7 Golf GT will clear the 245 brakes.

They are called the Dijon wheel. 

We run them on our Golf 245 in winter, same as these:

As to whether the wheel will fit flush in a mk3 Octavia wheel well, I don't know the answer to that sorry.

Thanks all for the info, much appreciated 👍

Can you buy an 18" steel wheel the same offset as the stock alloys cheaply?

 

Just thinking another option is to buy one of these then stickna used tyre with a few miles left on it from your alloys next time they need changing.

 

Then you'll not be bound by the restrictions of unequal wheel sizes and pretty much get a free tyre.

 

Not sure how common 7.5j 18" steel wheels are though!

I haven't seen any 18" steel rims that would fit, only up to 17". Even then only 6.5Jx17 ET38 and ET41. The ET38 being available in both standard 20-hole design and the hybridrad design, and the ET41 being only available in the hybridrad design.

 

Here's the 6.5Jx17 ET41 5/112 57.1 hybridrad design on oponeo.co.uk

Although it might be best to stick to 205/50R17 tyres with the 6.5J ET38 or ET41 steel rims, you could fit oversize 225/45R17 tyres to a 6.5J rim. It does go against ETRTO recommendations to fit a 225/45 tyre to a 6.5J rim which requires at least 7J rims for 225/45 tyres. And remember 225/45 tyres on the Octavia MK3 are usually fitted to rims that have an offset of between ET49 and ET51, so you would be increasing the front and rear tracks by at least 16mm if using ET41 rims.

 

You can now get the latest Goodyear EfficientGrip Performance 2 tyres in size 205/50R17 93W. Goodyear claims that they have class leading wear rates. Goodyear compares them to tyres such as Bridgestone Turanza T005 and Continental PremiumContact 6. By going for the narrower 205/50 instead of 225/45 you benefit from a wider front and rear track when comparing ET38 to ET49 or ET51, less wind drag, less unsprung weight, more mpg, and perhaps a more lively and enjoyable feel. Fitting wider tyres sometimes actually makes a car less enjoyable to drive not more.

 

Fitting 225/45 to narrow 6.5J rims would give improved ride comfort as the narrower rims help the sidewalls to flex more easily. However, mounting 225/45 rims to ET38 or ET41 rims may move the edge of the tyres too far outwards towards the edge of the wheelarches. Also, fitting 225/45 tyres to narrow 6.5J rims could make the handling/steering feel a little less sharp compared to mounting the 225/45 tyres to 7J or 7.5J rims. However, you would probably soon get used to the new feel...it depends on what sort of setup you prefer.

The thing is, if you don't have matched tyres across the Axel you have to use it for minimum use and are limited to 50mph so arguably can just get a space saver as you don't really gain much from the larger steel wheel.

Most likely it'll just be used to get home and then to a tyre fitter for a new one, so may as well just get the lightest and cheapest solution.

 

If you can go to full size then you can use it as normal and don't need to worry about changing the tyre in any hurry.

 

Going in between just makes it bigger and more expensive than a space saver but without any additional benefits as far as I can see.

morning all,

Had my 245 a few weeks now love the car but!

i am going away and don't like the having no spare wheel kit, but I have a set of 17inch wheels would these fit over the big discs?

also I would be buying a scissor jack and brace not sure on size of wheel nuts ?

pic from google as mine are 17s 

Open your fuel flap and you can see all the sizes that will fit

 

Or just quickly whip a wheel off, fit it and see. 

tbh if it doesn't fit, it's not really a concern anyway.   You'd likely not get a space saver over them anyway.  I know I can't get my spare on the front on my Honda, it's quite normal.

 

If you get a flat at the front, just pop the spare on the back and swap that wheel to the front.   It's an extra 5 mins IF it happens.
