Tyre choice on Campagnolos

[Matt No VAT]

I'm deciding which tyre sizes to go for on my new coffin spokes, and I'm struggling :confused:

At present I have 205/50/15 on the front and 225/5015 on the rear - most manufacturers have stopped making the 225/50/15's now.

Was quoted £735 for the above sizes 205/225 combination for Yokohama A048's.:eek:

Only other option is to go for budget tyres and that choice sacrifices grip.

My Hawk stradale is a road car so don't want the wheels to get too wide and tramline - the balance at the moment I feel is just right.

Can anyone else with the 15" x 8" coffin spokes tell me what tyre sizes they went for?

Any advice would be much appreciated

Sando - Can you PM me re: wheel centres etc?

Michelin TB15:
F: 18/60 - 15 TB 15 = 215/55 R 15 86V wheel size: 6" -8"
R: 23/62 - 15 TB 15 = 270/45 R 15 86V wheel size: 8" -10" or as above.

I think its only fair that we tell people that TB's are a great tyre but are not really designed for the road and their life expectancy is going to be a fraction of a road tyre. I am told in the region of 3000 - 5000 miles but am willing to be corrected on that :)

This is why I suggested TB15. It will last maybe 7000Km with reasonable (non-track) use.
I don't think many Stratos (even replica) owners cover this distance over a year.

Will 270s fit under the Stradale rear arches?

No they won't.

TB5's would be the more sensible option for the road?

[tryphon]

TB5 are like butter, TB15 is more sensible.

I thought they were a harder compound for higher temperatures?
In the old Michelin codes I thought the higher numbers were the softer compounds. I remember the PB wet being 20's and the softest slick being SB20........I could have it all the wrong way around though, it was a long time ago.... ;)

Just had a look on the Michelin site Tryphon.
Michelin Sport (http://www.michelinsport.com/sport/front/templates/affich.jsp?codeRubrique=600&lang=EN)


-The Seventies, ever onward…. As motor sport technology evolved so a special tyre was required. For the amateur racer the TB in its intermediate compound form, known as the 15, provided the best compromise between a race tyre and a multi-purpose product.
It returns with an additional card up its sleeve:Today, the TB range is road legal.
TB 15 : The dominant tyre equipment for the rally stars of the 70'
TB 5 : Same tread patern with a harder rubber compound for use in ambient conditions above 20°C

Rob, you are right.

I remember my brother ran his Nova in the 1300 Festival rally on a Norfolk USA air base in the early 90s. He ran all day nearly on the same set of TB15s. Richard Walsh from Thurlby Motors (Lincs.) went through about three or four sets of brand new TB20s in his similar Nova on the same day. All he'd brought were TB20s and it was warm and dry. We couldn't bear to watch all the money go up in smoke. I know they were only 13", but proper Michelins were never what you'd call cheap?

You guys are right I mixed them up TB5 is harder than TB15 and the more sensible choice.
