Tire Purchasing (Nationwide Shortage)

[PianoAl]

The Bridgestone Turanza Quiettrack (235/45R-18) have been recommended here because they are so quiet.

When I tried to get them at Costco (and at Les Schwab) I was told that they are backordered. I looked at Tirerack.com, and was told in a chat that "You need an Extra load rated tire for that vehicle and those are just a standard load."

The rep also said, "
But you can go with a slightly larger 245/45 https://www.tirerack.com/tires/tires.jsp?tireMake=Bridgestone&tireModel=Turanza QuietTrack&partnum=445VR8TQT&tab=Survey Larger tire so more load capacity. Those would be fine"

How does that work? The larger tires would fit on my wheels??

Thanks for the help,

Al

A 245, in general, is only 1.5% larger in diameter than a 235. However, if you can get the tire specs, you can compare more closely. Below are the 235 and the 245 listed. Just comparing revolutions/mile, the difference is only 1.2%. Looking at the Michelin OEMs, they have a spec of 790revs/mile, so the diff to the 245s is only 1%. The tread width is wider, so I wonder how much of a range hit they'll make.

Does this offer low rolling resistance?

Here's an important question: Les Schwabb recommended the 235/45R-18 with no mention of it being inappropriate. Should I just trust them and purchase the 235s from TireRack.com?

For me, the reduced road noise would outweigh any slight decrease in range.

They are right. Only the 19 and 20” QuietTracks are XL rated. I’d follow that recommendation.
