Possibly some stupid questions herein.

I am after a spare wheel to replace the 10 year old foam can in my Accord. The wheel size is 225/45/17.

I can find space savers on ebay at size 135/80/16. Would these fit? Hundred quid for one too, mental!

The alternative would be to source a fifth alloy wheel and put a cheap tyre on. How would I know which alloy fits other than the Ebay description of 17" Accord alloy?

Does the handbook show a size for a spacesaver? Have you checked the wheel well to see if a full sized wheel will fit?

For some vehicles the sizing is critical. on my MINI loads of FleaBay sellers try to offload 125 section spacesavers from Rover 25/45 type cars. Whilst they will fit as a spare wheel on the hub only a 115 section wheel will fit in the wheel well.

I will have a check of the book and measure the spare wheel well. I guess a 135 section s/s will fit in the wheel well if the wheels currently fitted are 225.

Not necessarily.

That's the whole point of spacesavers.

Can you imagine a 19" spare wheel in a Corvette boot.

You might not even have a spare wheel well.

I definitely have a spare wheel well, it has my sockets and spare bulbs in. Will need to get the tape measure out.

Would it matter that s/s is 16" diameter and not 17"?

As Vikingaero said ,read the handbook.

If it's any good it'll list the OEM wheels and hopefully any spare wheel size that might have been optional

when new.

Jack the car up, take a wheel off, and chuck it in to see if it'll fit. FAR more conclusive, and won't take a LOT longer...

So long as the space saver fits over the brakes (or, so long as you don't mind a shuffle-about, the back brakes) the rim diameter's almost irrelevant. It's the overall diameter.

225/45 17 = 17" (432mm) + (2x (225 x 45%)) = 634mm
135/80 16 = 16" (406mm) + (2x (135 x 80%)) = 622mm

So that spacesaver's going to be a tad shorter than a full-fat, but not really enough to worry about, given that it's only a stop-gap-get-you-out-the-gutter.

But will that flat, muddy, wet full-fat fit in the boot...?

Good advice 2CVs, I have measured up and can fit a full size wheel in the spare wheel bay. I think I'll go for whatever is cheaper out of the spare alloy or space saver.

Common with cars of a certain age. The fad for deleting the full-size spare came on with the tax based on emissions. Leaving it out not only saves the manufacturer money it can also get the car into a lower tax bracket by having to lug less weight about.

Bear in mind if you do have room for a full-size spare only if the tyre and rim is the same size as the others will you not not be limited to 50mph/80Kmph as you are with a space-saver. Some cars with alloys have a full-size steel spare of equivalent diameter to the alloys but a different tyre and rim size. These are limited to 50/80 too.

Also, your better off fitting the spare to the non drive axle. The diff with thank you with a lot less wear.

I have sourced a 205/55R16 Accord alloy which = 631.5mm given TooMany2cvs' equations, therefore only a few mm difference to my current wheels.

This would be limited to 50mph, fitted to the rear axle and would fit in the spare wheel well.

Hopefully I have that correct. Thanks for the help with this smile
