Tire Pressure & RFT
Is anyone else's RFT slowly losing pressure, or is it just me?
All 4 of my tires lose about 2PSI per month or a bit more, brand new from the dealer. Maybe it's the RFTs... not sure. But I've definitely noticed that a difference of 2-4PSI in the tires under pressure makes the ride a LOT harsher. Once they're back to 36/38 the ride is much, much smoother. Maybe this is why people hate RFTs - they're sensitive to pressure?

I agree with the "cold weather" drop in pressure.
I have 16 tires to care for.....checked them the other day due to the recent temperature drop and all had dropped 2 to 3 psi (except one on the Integra that was down 12 psi...woops) It's that time of the year people.......check your pressures !

I has learnt that RFT suppose to lose pressure quicker than normal tires. 2 in a month is about right.

This thread is lame. All tyres will slowly lose pressure. Rubber is not 100% impermeable to gas. Especially gas under pressure.
While it seems trendy around here to bash RFT's, is there any credible evidence that they lose pressure any faster than any other tyre? I doubt it. |

How much did the pressure vary from summer to winter when you checked it? If it didn't change, you either checked the pressures in a heated garage after the car had sat there for a few hours or more (a bad idea if the ambient temperature is much different outside), or your pressure gauge was faulty. From an ambient average of about -25C in the winter to +25C in the summer (the sort of temperatures Ottawa can see in any year) requires about 10 PSI of pressure change, so you were either running dangerously low or excessively high pressures in the tyres at some point if you didn't add or remove air for a year.

I run 2psi higher than recommended for daily use as my commute is highway speeds, and I feel a slight better steering response with a bit more pressure. |
