Bridgestone – Bridgestone Exedra Touring & Cruiser - Rear, including G702 and G702R fitments, G722 and G722R sizes, G526R and G546R options, G850 rear radials and G508R MAG Mopus sections, is the rear-wheel half of Bridgestone's long-running touring range. Rear tires on cruisers and full-dress tourers absorb the torque, the passenger and the luggage, so these casings are built with reinforced plies and a tread compound aimed squarely at mileage and load stability. The block layouts keep a wide center band planted for straight-line comfort, then open into deeper shoulder grooves that clear water when a rider leans into a wet on-ramp. Sizes span 130/90-15, 150/90-15 and 150/90B15, 150/80B16, 170/80-15 and 180/55ZR18, which is exactly the spread that older Japanese cruisers, shaft-drive tourers and custom builds need. Speed ratings from P through W are represented across the range. Fitting the matching Exedra front and rear keeps the chassis balanced instead of mixing profiles that fight each other. Sidewall speed ratings differ between otherwise similar patterns here, so check that the rating you order at least matches the original specification.
