I need to to replace the front tire on my T-Bird. I am sticking with an Avon AV 27 replacement but would some like advice on the what manufacturer and size of inner tube to order with the tire.
Thanks
Mark

Get the pirrelli tube if you can they have a right angle valve, which make them some much easier to check and inflate. The correct size to suit your tyre which would be a 110/80 18.

Hi Tbird95,

First, what a great name! (I also have a '95 Thunderbird).

My Avon dealer has normally fitted Michelin inner tubes (interestingly made in Italy). Both Pirelli & Michelin are top quality makes, and I don't think you can go wrong with either.

JWoodsie has a point about the angled valve, perhaps more important on the 16" rear, but if you don't like the look there are right angled valve add-ons available that can be carried in your tool kit - they are about £3 from accessory shops.

However, something for you to mull over! I replaced my AV27 with an Avon Azaro-ST AV45, and found it a step up in grip. I did contact Avon direct about this tyre and whether I could mix it with the RL30 until it also needed replacing (with the AV46). I also have the AV45/46 combination on my Sprint (17"), and recommend you think about the AV45 front for your Thunderbird. It was a good choice for me.

Ciao,
Geoff

Yeah I have the Azaro Av45 on the front, and th RL 30 on the rear, its a pretty good combination, I was after the AV46 for the rear but the bike shop talked me into the RL30, as he said I would get better mileage from it. No arguments there, I havent had any moments from it either. Could have something to do with the fact that I ride like an old woman.A very old woman. :-D

Hi JWoodsie,

I guess I ride like an old woman too, or at least I know what you mean. Rather than our riding style, I think it may be the riding/road conditions.

I am lucky in havin two 16" rears, one with the RL30 and the other with the AV46, and able to change between them.

The RL30 is a Touring tyre and good for long straightaways and upright riding. The AV46, being a Sport touring tyre, is great for the twisty bits.

Anyway, whichever your rear choice, the AV45 works well with both. I'm glad you found the AV45 a good choice for the front too.

Ciao,
Geoff

I used to run the the Avon AV45/RL30 combo - I didn't find the RL30 to be very good for mileage, I'm afraid.

When I switched to the AV45/46 combo, I found it to be dramatically better on handling and I have no complaints about the wear.

I usually buy over the internet and then have a local shop fit the tyres. Since I've found little or no price advantage with respect to the inners, I let them fit whatever they have in stock but I do specify the right-angle valve for the rear.

Guys thanks for your feedback. I am going to order an Azaro Av45 and run on a RL 30 Combo until the fall when I will replace the rear with AV46.

I am having difficulty sourcing a quality inner tube of the right spec so any help in that direction is appreciated.
Cheers
Mark

Mark...

Just noticed you live in Houston so it gets pretty bloody hot right? Whilst I have no recommendations over brands, one thing I was told by my local shop is that thin inners are better than thick ones in Texas. Because of hysteresis, the thicker ones will tend to overheat more than the thin ones.

I don't know if this is valid or not but thought I would offer it up. Why not go with whatever your fitter recommends - or are you doing it yourself?

Hi Chris & Mark,

I had to look this one up:-
Hysteresis represent the history dependence of physical systems. If you push on something, it will yield: when you release, does it spring back completely?

Chris, it is interesting that your fitter mentioned this. I am a member of a "Tenere"/Enduro forum and there are alot of guys there who use the 'thicker' Michelin & Pirelli inner tubes and travel successfully into the Sahara regions. I suspect there is more to this, like the compound the tube is made from, etc..., rather than the thickness perhaps?

For Mark, local knowledge is important and the nearest Triumph dealer must use a tyre shop? They should be able to recommend and supply a quality inner tube.

Another avenue would be to contact one of the major company's technical departments and discuss the options and outlets? Their details should be on their websites.

Good luck.
Geoff

Hysteresis in tire tubes is a new one on me! I'm familiar with the effect in electronics and it's kind of similar to inertia: not a resistance to change specifically but rather a delay in change. Sort of the opposite of compliance.

Aside from that... Mutato came with thin inner tubes (Michelin?) that leaked 3-5 psi per day regardless of whether the bike was ridden or just standing in the garage!

I went to Contininental heavy-duty innertubes when I changed tires and the leakage is down to 1-2 psi per week. Big improvement! It saves a lot of pressure checking during a day of riding. :wink:
