I wouldn't suggest to relay on Canadian Tire in Bancroft.
Remember last rally cross. They didn't want to deal with John's flat gravel tire when he went there.
Better ask John he probably will be able to answer the question.
W/ Julien and Marie-Eve not entering (??) The Lachute van may not be there (and Joan's rig does not have such a machine.
Mind you that I have not spoken to Julien, Nick or Yannick, but would hate to see you stranded Matt.
As far as CT and my tire, I had a gravel tire come off the rim at a rallyx from gravel getting stuck in the bead, CT (In Markham, not Bancroft) put it back on but ripped the bead in the process and didnt even tell me. The lead to last minute scrambling before a drivex event last weekend. I wont take gravel tires there again, next time, no matter who does it i will watch them
I know that its not possible for everyone...but the best deal is to get there whit all your tire monted on rims...(one of the benefit of rallying a justy ..13" mags are cheap )
at pines i mount all my regular (nonrally super wimpy side wall) tires on oem (becose they are strunguer then after market) steel wheels whit iner tubes...mostly becose if there snow...there wont be enough to smooth the road...steel wheels are ugly and heavy...but they will bent... not crack & brake like most aloy mag + you can get them for 10$ at the scrap yard...a litle bit of paint and your good to go.
Most Can Tire techies have never seen such a tire, and gravels are tricky (and tubes can be too). The Bancroft CT can be reasonably good - one year we just walked in and told them we needed to use their machine for an hour and we did about 20 tires - but unless you look like a pro team and walk in with lots of swagger they may not give you the same deal!
Still, we should give them the business - they're quite supportive.
Also I have used gravel tires and a few ice tires still for sale.
