Tyres for '72 oil in frame Bonnie.
« on: April 27, 2017, 08:58:46 AM »
In the next month or so I'll be getting round to fitting tyres to my T120V Bonnie. Can anyone advise, recommend or just say what tyres they have fitted or have experience of. The last tyres I bought were Battleaxes for my Suzuki Bandit a few years ago but doubt they would be suitable!

I'd sooner go for function over form but don't particularly want something that looks ultra modern. The bike won't do many miles so wear rate isn't a problem. It will mainly get used in dry weather but I'd like it to be controllable on wet roads. I believe I left my loonatic days behind when my hair went grey but I'd still like the tyres to be fairly sticky just in case.

Tyre sizes are,front 100X90-19. Rear 110X90-18. Both are on spoked rims so will need to be tubed type.

Thanks in advance for your replies.

Tyres, oil, Indian Red....it's like asking what cheese is best!
My long departed T120V was the best handling bike I've ever had (reliable too, shame it was so ugly!) so my advice would be to fit something at the higher end of the market. Think mine had K70's but it was a long time ago.
(Dolcelatte, since you asked... ;))

That's a ridiculous comparison....Cheddar, preferably extra strong, is without question the best cheese.
Dolcelatte Pah.

I did use to run a K70 on the back with a Road Runner on the front, or vice versa, I traded my memory for grey hair. I reckoned this gave the best handling. But with the way tyre compounds have improved since then I was wondering what the modern day equivalent is. I'm fully expecting someone to say Maxxis are a good buy, to my mind they were the equivalent of the Kamikazi Skid Masters of the 70's.

Avon Roadriders?

I notice your '?' Is that what you've got fitted. I've google them looking for feedback but not found much.

No, but I probably will fit Roadriders when the time comes. The '?' was because it was a suggestion.

There seems to be plenty, as Roadriders have been about for a few years.

Thanks for the link L.A.B I must have been looking in the wrong place. Probably had cheese on my mind.

If you do happen to decide on Roadriders, note that the 100/90 - 19 front is 109mm wide, so I suggest you check you have adequate mudguard clearance, also the 100/90 isn't recommended for the standard WM2 (1.85) front rim, 3.25 -19 is the recommended size.

I've got a Dunlop ally WM3 rim fitted which measures 2.17 wide at the bottom of the flanges and only just gets insideAvons tolerances. Tyre width should be ok, in the past I had to deflate it to get the wheel out.

I'm using the Roadriders on two bikes and find them a good all weather tyre for my riding.

Thanks Murdo I think that's what I'll be going for. Just got to decide whether to get them cheap on line or more expensive and have them supplied and fitted.
