We were 5kms out of Kincardine when my Left Front RV Tire (dual axel) blow out...when my TPMS alert went off when the PSI went down from 65PSI to 48PSI I slowed down immediately and within secs the PSI went to 4...I put on my hazards...pulled into a nearby business lot off of HWY21 and called CAA...Rowes was there in 20mins...the driver (Chris...man deserves a raise) changed the tire w/the spare I had on the back of the RV. Thank you Rowes :)
