Tires . Which thinks that saves more fuel ?
My car brings tires 175 / 65R14
I searched the lighter rims and found the opel corsa a gsi . 17,2 lbs (7,8 kg) 5j x 14 4x100 et47,5 carries four tires 185 / 60R14 Michelin energy + . Two of the tires were bad. I've changed some 175 / 65R14 primewell ps880 . 175 / 65R14 is more popular. I can save by switching the measure 165 / 70R14 ? Do I best with 175 / 65R14 ? |
Get Bridgestone potentza Re92's. 165/65R14. Best tire in terms of MPG by far.

I think the 165/65 R14 are too small.
165/70 R14 are very slightly bigger than the original 175/65 R14s. You may consider using 165/75 R14. Those are available from Michelin and others and are 1 cm taller than the 175/65 R14s. (cracking the numbers: ) The second number is the height of the sidewall as a % of tire width. So 175/65 = 175 mm * 65% = 113.75 mm high. 165/65 = 107.25 mm, that's 6.5 mm lower than stock. 165/70 = 115 mm high, that's 1.25 mm higher. 165/75 = 123.75 mm high, that's a full centimeter more. If you go for 165/75 R14s remember to add 3.3 % to your odometer readings, as those will display 3.3 % less than stock on those tires. Likewise, the speed shown is less than stock; as speedos usually show a substantially higher speed than real, it will only become more precise. |

You can explicrme that is. here's tire saving fuel. It's the same ? narrower versions need a higher profile. to have an equivalent diameter . Is there much difference ? 175 / 65R14 and 165 / 70R14 previously used wheels with tires 175 / 70R14 . consumption increased slightly. It was better in the bumps. was best at speeds of 90km / h ( 56 mp / h ) or higher. lower rpm . Less engine noise. here in Spain and in Germany. are said to michelin tires are best. and that more lasting . are the more expensive price . |
Those 175/70 tires have a 8.5 mm higher sidewall than the 175/65s.
So they were about 3% bigger than the 65s. If you did not compensate for their size in the odometer readings, and you seemed to use 2% more fuel on them, in reality they were saving you 1%... If 175/70 R14s were OK, then get the 165/75 R14; those are just a few mm taller. |

here allow a limit of + -3% in diameter. 165 / 75R14 is 3.5%. not allowed. |
