Rebel Tyre Size?

Post by SithDowell » Sat Jul 21, 2018 6:04 pm

Like it says on the tin - can anybody tell me what size tyres go on a rebel?
Interrogated Google to within an inch of its life and came across a crossply size of
5.50 - 12
Buy I don't know how accurate that is. I also don't know what the radial equivalent would be. Something like
140/70 R12??
Thanks for any help,
Sith

I'm not very good at sums but it seems to me a 5,50 tyre would have a height of about 11 cm
so you would need more like a 155/70, if that exists ?

Thanks Dark Star, looks like you're pretty much on the money.
Just had a wee blether with long stone vintage tyres who were more than helpful. Turns out 5.50 12 is the Rebel tyre size, and the closest radial equivalent would be either
145/80 R12; or
155/80 R12
Had a go on a tyre size calculator and found a couple more sizes that might be more common:
185/60 R13
165/65 R14
But then again, they might not.

145/80 would be just about spot on if that exists.

I haven't worked it out but it seems to me 185/60 x 13 or 165/65 x 14 would be too big - don't forget you have to add the diametre of the wheel to the tyre height :wink:

I think 145/80x12 was used on a Mk1 Fiesta.

As you are finding, calculators to give alternative tyre sizes are fine, but they don't tell you what is actually commercially available at a reasonable price. Not all tyre makers make tyres in all sizes, and some older car sizes (eg 14" for the Scimitars) are typically only available today as "van" tyres, where the tread and sidewall flexibility are completely unsuitable for a light road car.

There is no ideal shortcut to this conundrum in my experience, but a good place to start I've found is National Tyre. They seem to list an astonishing range of brands, most of which I've never heard of. But hey, do you want that tyre or don't you ? :lol:

In your four options, they list nothing in 12", only 1 in 13", but no fewer than TEN options in 14".

This clearly tells you which sizes are widely available and which will be a problem. I would advise, then, that your strategy should be to simply google the ideal size - 1X5/80-12 - and see if *any* viable suppliers come up. If they do, then you can explore each one in turn, as the numbers you're dealing with won't be huge.

If you don't get anything there, then I'd do the same again with your 13". It may be that National only lists one, but others may list several, so just test that out. If that search doesn't throw up any viable source either, then it's pretty clear that the 14" size is the only realistic option. And with so many available, other factors then come in, such as price, recognised brand vs budget, where's your nearest/most convenient fitting station, and so on.

I am presuming that you are going to change the wheels to suit whatever tyre size you settle on? :w

Happy hunting - most of us have been there !

Thanks for the reply Drcdb15.
Yeah, when I found that the OE tyre size was a cross ply size I knew I was in for a "fun" time :w
I had assumed that since there are about a squillion Mini fan clubs out there that it wouldn't be too difficult to find a 12" tyre in the right size. All together now:
HA HA! :oops:
As for finding radials in the sizes I mentioned, I use a website called Camskill (don't know if I'm breaking forum rules here, but I don't work for them I just buy a lot of rubber off them). They don't fit but do deliver and have almost any size you want...as long as its radial! :roll:
Anyhoo, found some tyres B rated for wetgrip and C rated for economy with a 69db rating for less than £30 a corner, so I'm happy enough with that :D
Thanks again for all the advice and replies,
Sith
