Max wheel+tyre size for Flow Smart trainer

Post by Rumik » Thu Nov 08, 2018 10:52 pm

I have purchased a Flow Smart trainer and find that I cannot mount the bike on the trainer because the wheel+tyre diameter appears to be too large - the tyre is 45-622 giving an overall diameter of 712mm

Is the only solution a smaller tyre?

I think a 35-622 (giving an overall diameter of 692 mm)would maybe allow the bike to fit but anyone got any firm data on what does fit?

It is frustrating that Tacx not state a maximum diameter for wheel and tyre in mm so that it would be easy to know whether your combination would fit before you buy?

Firm data is Tacx Trainer Tyre, T1397, 32-622.
From the manual it follows that the maximum size of the wheel (with a tire) for your model - 700 mm.

Probably, a 35-622 tire will also work.

45-622 is a very large tire. If you try a 32-622 or 35-622 tire, be sure it is compatible with your rim and it has smooth tread. Rims made for very large tires may not work with tires that are considerably smaller. Your rim should have a specification for the smallest usable tire. Of course, the specifications are partly based on safety for outside riding, so because you are on an indoor trainer, you can probably fudge it a bit.

Most road bike users are going to have no more than a 28-622 tire and more commonly a 23-622. We have tandems on our Tacx trainer, including a Flow Smart and use a 622-23 Vittoria trainer tire. I am not at all certain that a 32-622 will work with a Tacx trainer and even less certain about a 35-622, so you might want to send an email to support@tacx.com and ask them.

Many thanks for the replies. I'll post when I have a working solution just in case anyone else is interested.

Just in case anyone is interested, I replaced the 622-45 tyre with a 622-38 tyre and all is now well and I'm enjoying using the trainer.
