[Luke_PL]

Hi! Ordered roadtec back tyre few days ago and internet shop made mistake and sent me sportec M3. Should I send it back or give it a go? front is Metzler roadtec.
cheers

Probably better with the stickier tyre being the front rather than the rear, personaly I'd send it back and get them to send what you ordered in the first place.
