New trainer tyre on wheel on turbo

Equipment
1

Hi,

I have an Elite Tuo wheel on trainer and have just ordered a new trainer specific tyre after the last turbo tyre developed a bulge and split.
Both are 700 x 23c and I’ve been using the old one for the last 7 years so owes me nothing. . I appreciate I will have to re calibrate and do a new ftp test but just wondered if I am likely to see an increase or decrease in power as a result of the change?
Just asking for previous experiences please.

Just for info the old is a Halford’s generic turbo tyre and the new one is a Schwalbe Insider.

My understanding is that the Tuo is a smart trainer and has its own power meter (i.e., the unit itself sends power readings to whatever training app you are using), so a new tire should not have any effect on your power readings.

Hope that helps!

Thanks for the prompt response.
Was rather hoping it might be a bit less effort :grin:

But it’s a wheel on, it cannot measure power but only estimate but the estimate is very dependent on tyre/ tyre pressure, temperature and maybe other factors. My elite nero comes with big caveats regarding power accuracy in the manual. It will definitely need recalibration with the my etraining app

Sure, but the OP already mentioned recalibration so seems he has that covered (and is likely why Zackery didn’t reiterate it). I can only hope that is also standard practice with each workout as that is the standard recommendation for wheel-on trainers.

Recalibration will indeed be necessary!

@Freddy2255 DC Rainmaker has a great video that goes over the trainer’s calibration process here just in case you need it. :slight_smile:

I used the Continental Hometrainer tyre when I used a wheel on trainer.

The 23C variant has 110psi as the recommended inflation pressure. How does that compare to the Schwalbe Insider?

It’s max of 145 psi, but my trainer recommendation is 110 psi :+1:

The 110 per the trainer info is a “safe” value as that pressure is common for many tires that might be used on a trainer. The 145 psi value is very rare and not something I’d even bother to aim for. I rarely see a need to exceed 100psi for a tire, trainer or otherwise.
