Tyres sizes comparison chart?

Type 'tyre size calculator' in MSN or Google and you will be spoilt for choice.

Trouble is you end up with these things with so many bloody variables you can't work out what you want !

We're still hunting for "9X16" alternatives. What WILL fit on a 101's rims ? And not look silly and/or need wheel arch extensions.....

Steve

Ah well! I can lead a horse to the water but I can't make him drink :-)

Huw

Am I right in thinking that 9 x 16 have 100% aspect ratio ?

Steve

From

9.00x16 are 100% aspect ratio which is metric 250/100r16. The nearest actual metric size is 315/75/16 which is usefully wider than standard. For other compatible sizes, enter 250/100r16 into one of the common calculators and any alternative you like to see whether they are suitable from the gearing aspect.

Hope that helps.

Huw

AH ! Thanks Huw, that does help a lot.

Heres one I found to be very informative.

On or around Thu, 15 Sep 2005 21:30:17 +0100, steve Taylor enlightened us thusly:

yes.

there are some, I believe, something like 235/100R16, or somesuch.

failing that... something like 35-10.5R16 if they're available. wider ones are certainly available, but would make steering a bit like work without a PAS conversion.

Coo:

has a thing about "silverstone extreme", which looks a handy tyre, and lo! is available in 35-10.5R16. 158 quid a shot, mind.

If that's a bit pricey, you can have a cheapo called danubiana, for 86 quid... in 900x16. speed rated at 80Km/h though.

There are also simexes in 35-10.5R16 and 34-10.5R16, but they're really expensive.

A fair few people have gone for 255/85r16. Its what im putting on mine once i get round to working on it!

They differ very slightly from the 9x16s (a tad smaller). But are about as close as you can get while being a standard tyre size.

You can buy this size from craddocks and other tyre places.

Here are some pictures of the same ambi (Hobbes) with bargrips and then 255/85's on it. Pictures stolen from the 101 list.

quoted from the 101 group:

Its tricky to find anything with a 100 sidewall in the UK. I've been looking.

proper 255/85's can be had for £80-£100 per corner, which aint too bad.

In theory yes.

Trouble is 9 x 16 can actually mean lots of different sizes. My 9 x

16 Petlas tyres were much larger than the mil bargrips that came off, even allowing for the tread wear. So it can be a bit of fun working out what size you need.
