Considering the cost of fuel today, that is one of my concerns, and questions. I do not recall seeing much mentioned in comparisons about mileage. Is that to say they are all the same? Or is there a noticeable difference, say between the GY-LS and the Michelin Pilot Exalto? Even a couple of miles per gallon could add up quickly. I have 85,000 on my second set of GY-LS' and want to get then replaced. Has anyone drive on the GY-LS and a Michelin and seen any difference in fuel economy? Thank you.
Because as an oem tire the car itself gets the same EPA mpg, the tires are similar in terms of fuel economy. All things being equal, (they are far from it and you might question if they ever have been or it is just an intellectual construct.... ) mpg has played a part (been a factor) for me. It remains an important selection tool. There can be a huge difference in quality of the tires. My take is when you drift from oem tires, unless you have done the research for those tires that will match oem rolling resistance (match mpg) , it is almost a given that fuel mpg will suffer. The question usually now becomes how much.
At this writing I am @ 105,000 miles on my GY LSH's. Looks good to go to 120,000 miles (due a rotation in 5k miles) . So say I switch to a tire that gets 5 mpg less (pick your number, any number then show us ( YOUR )the math) Right now, I get an average of 50 mpg- 5 mpg= 45 mpg/100,000 (round numbers for the sake of argumentation) = 2000 gals/2222.22 gals, diff of 222.22 gals @ 4.39 D2 corner store= $975.56 premium MORE per 100,000 miles. This is a min and there is a question if the other selected tire can even last 100,000 miles!!!!
So if a Toyo TPT costs 62 per and a Michelin MXV4 Primacy costs 120 ; that converts to 15/8 tires respectively. For me it remains to be seen if the TPT can match the GY LSH mileages.
