Do I have to buy a trainer tyre?
I'm thinking of buying a turbo trainer but don't want to faff about changing the rear tyre every time I switch from trainer to road. Can I use a trainer with just my normal tyre or is the performance compromised by not using a 'special' trainer tyre?
you can use the trainer without the trainer tyre and it will work just fine. the only thing is though, that this will wear down your rear tyre pretty fast. after about five sessions with a non-trainer tyre on my turbo trainer, the rear wheel was noticably balder than the front - so i invested in the trainer tyre, which i keep on my spare set of wheels and then i change the wheel each time i need the trainer.
the trainer tyres are good because they are VERY hard, and wear down slowly.
so yeah, it's not a necessity to buy the tyre, but its probably advised.
