Vehicle: 2007 Suzuki Grand Vitara.
The OEM tires for this SUV are 225/70R16 Yokohama Geolandar H/T G92C. Speed rating H and a UTQG of 280 BA. I had read in Suzuki forums that these tires from an overall wear perspective are pretty dismal. Sure enough, just turned 30K miles and needed new rubber.
Started searching around for tires with better wear numbers and reasonably priced. Found Goodyear Integrity in the proper size at Sam's Club for $87/ea. Specs on these tires were speed rating S and UTQG of 480 AB. Lower speed rating but much better wear numbers. So off to Sam's I go.
Get there, order up the tires, start the checkout process. Tech is putting in all the info and then the computer spits out something about these are the incorrect tires for that vehicle. Tech states that OEM tires had an H speed rating and these tires are S speed rated and you can't go down two speed ratings. In his words it would cause "adverse handling" and vehicle will "squirm" and "wander" on the road. My "baloney detector" immediately went into the red zone and I smelled "upsale". My words to him was this was an SUV that never sees more than 80 MPH. Why would a speed rating of 112 MPH vs 130 MPH make any difference? If it was a Porsche or Corvette, sure, that speed rating is important. We went back and forth for a few minutes and then the tech checked the tire label on the SUV itself. All it said was "225/70R16" with no speed rating. At that point the tech agreed to put the tires on and I was on my merry way.
So BITOG's...was I wrong? Is the lower speed rating going to cause problems? I haven't noticed any difference in the vehicle handling other than it no longer has a tendency to hydroplane in the wet because the old tries were worn out. And that's on the good side. I suspect that the reason H rated tires are OEM on the Grand Vitara is because it's also sold in Europe where average speeds are higher.
