another tyre thread
« on: 02 February, 2009, 06:03:18 PM »
Hi guys,
i know that this has been done to death already & ive read most of the threads...(excellent post by Andycbf incidentally) but after all the debate, ive decided to break from tradition & not go for the PR2's.  Im heading for the Avon Storm ST.  Looking at the M&P website, ive seen a special offer for a 160/60/17 rear but a 120/60/17 for the bargain price of £144.99
Trouble is, the front tyre size stated on the honda website detailing the specs of the Biffer is 120/70/17.
Whats the difference, forgive my ignorance, but is it the height (profile) of the rubber from the base & would it have a huge effect upon the handling/braking/grip etc. :187:

If so, then that's fine as they are quoting a price of £163.99 if bought individually.
Also, id rather not take the wheels off myself & i cant be trusted with anything mechanical & would rather have a drive in/drive out service.  So anyone in the Wigan area who can recommend such a service would be great!!
Thanks for the help in advance guys.
cheers
Andy

I have just put Storms on my bike and the manual agrees with the HOnda site. It's a 120/17zr17m.  Done a few miles on them and they appear excellent in the wet, have not seen any dry yet!.  Not that I had any complaints about the PR2 though.

Price for mine were £200 fitted, I tried 3 local dealers near NE Hampshire.  I suspect I could have got a better price some where but had just fixed a puncture and was not too confident in riding too far away!

Explanation
The aspect ratio of a tyre is the height of the tyre sidewall expressed as a percentage of the tyres width. To understand this more you need to recognise the meaning of the size markings on the sidewall of a tyre.

For instance a typical tyre size used today is 205 / 55 R 16 and this size can be broken down into 3 major areas:

205 - this is the width of the tyre expressed in mm.
55 - the aspect ratio, or profile of the tyre, in this case 55% of the tyre width.
16 - diameter of the rim the tyre is designed to be fitted to (in inches).

In this case the tyre sidewall height would be 113mm (205 x 55%).

It can be stated that the smaller the aspect ratio, the wider the tyre in relation to its height.

Important
You have to make sure you fit the correct size tyres to the bike. One if you fitted different sizes to the ones recommended it will have an effect on handling. Two, if the Police stopped and checked your bike and noticed they could book you for it. Three if you had an accident it could invalidate your claim as you didn't have the correct tyre sizes fitted.

Have you tried SMD in Leigh (in the town centre, literally), they do lots of bike tyres and also do a wheel removal service although you do pay extra for the service. I can recommend them and they regularly feature in Ride magazine articles.

thanks for the input guys, really appreciated, i havent heard of SMD in Leigh, but i will definitely be taking the bike there for the tyre change.  In my opinion, its much better having someone who knows what they're doing removing & fitting wheels to bikes, at the moment, i dont have the confidence to mess with things like that, so a little extra cost would be worth it.
Got a good price on the tyres too.  An ebay shop called black & round (not a dodgy niche porn site incidentally!) brand new £149.00 for the pair & delivery £6.95
Since the bike has only just had its 8k service (done at Cusworths in Doncaster - excellent by the way £210 for 8k service, fitment of GPS lead to loom & purchase of optimate 3 & fitment of lead to loom) the tyres were the original bt57s from new...
Anyway, thats enough waffle from me!
cheers
