I don't get involved with arguments about regulations but you owe Larry an apology!


APPENDIX I - APPLICABLE TO ALL MACHINES
1 TYRES
Owing to variations in weather conditions which can occur on the TT Course and in the interests of safety, only tyres having a moulded tread pattern will be permitted. No additional cutting of moulded tyres will be permitted. No slicks, cut or uncut, will be allowed. Metal valve caps (not extractor type) must be fitted. Valves must be of the short stub stem type.



APPENDIX II - APPLICABLE TO CLASSIC & FORMULA CLASSIC MACHINES ONLY

5 Tyres
No hand cut slicks or wet weather tyres will be permitted. Maximum tyre width, as stated on the manufacturer’s specification sheet, shall be 4.50” for Classic machines.
Tyres must be fitted with inner tubes.
Approved rear tyres for 500 cc machines are Avon AM22, Dunlop KR 124, KR124A and KR108. Other makes of tyre are acceptable providing the maximum width does not exceed 4.50” (114mm).

Full wets have never been allowed on Classic machines because they were not available during the period.

Jeff, if this is the case then in needs clarification in the Technical department as riders have been told NO full wets ( rider had to remove them outside scrutinneering this year), The race service vans dont even carry them now at the MGP. Larry made a statement that a Pireli full wet tyre would do four laps in the Dry, this is utter tosh at the speeds we do, lucky to get one lap.

Thank you Jeff - some of us can read !!

What is in the regs is not always kept to, we have been stoped from using full wets but allowed Pireli inters (wet).Could you do 4 laps on one set of wets at an average of over 115mph.

Another question, is a race at the MGP ever declared a wet race????
