Slight over-inflation: Problem?
I purchased a new set of tires for my Honda Civic (185/54 R14). I always keep 35 psi (cold) in them. When I checked the tire pressure (several days and about 20 miles of driving later), the pressure was 40 psi (cold). The installer put in a bit "extra". Any problem with running these little tires at 5 psi. Over for that short period? (I lowered them back down to 35 psi). Thanks!
Added (1). Sorry about the tire size, I typed it wrong: should be 185/65 R14, and it was checked when cold (40 lbs).
Most gauges are off by a couple pounds - but last time I got tires they were over inflated too, just adjust - tire changers really don't give a rats-azz about getting the pressure correct - and I suspect the gauge they use is just not very accurate.
If you checked the PSI after a 20 mile drive they were not checked "cold". PSI can certainly increase by 5 lbs after such a drive, that is not unusual and is to be expected. Checking "cold" can only be performed after the vehicle has not been driven in several hours.
Do not add any more than a pound or two over what is recommended by Honda. Anything more will unnecessarily make your ride more harsh and potentially prematurely wear your tires.
No, look at the max rating on the side of the tire many are over 40 anyhow.
First off you do not have a 185/54-14 tire. That is not a tire size. The correct pressure you should be running is what Honda recommends which is listed on the drivers door post. Run less and the tires will wear on the outer edges. Run too much and they will wear in the center of the tire. Run the correct amount and the tires will wear evenly.
Over-inflated tyres tend to suffer more punctures and may wear out the centre of the tread surface more quickly.
But 5psi over just 20 miles will have had no measurable effect at all.
I don't know what the recommended tyre pressures are for your car, but just stick to whatever Honda recommends and you'll be fine.
The guys that fit new tires never inflate them to the correct pressure. They just whack in some air. Always check your tire pressure soon after getting new tires.
20 miles will do little or no harm.
No.
No. It was a short distance. But Honda is fussy so keep the tire pressure to what Honda recommends. Gives even tread wear.
That small difference should not be any issue, just be sure you are using what the Civic specs call for
Have probably replaced 20 sets of tires… Always rotate so always replace in sets of 4. EVERY new set has been inflated above car makers recommendation - usually to 38 pounds cold on my home gauge. Tire shop guys say it's to help them round-out when brand new and to "set" the bead. I have no idea if that's bs… But I just make it a practice to drive new tires gently for the first couple days then set the pressure to car makers recommendation.
No - 40 pounds for a short while didn't hurt them.
- Why do people get mad over the fact that their cars require full synthetic oil? I work as a mechanic and found some people do not like the fact 2010 and up toyotas and Hondas and almost all 2014 cars and European cars require full synthetic oil. A majority of the anger comes towards toyotas and Hondas. Despite me explaining the increased intervals, they still get angered at the fact. Is it just me or does less time doing oil changes that save you more money in the long run end up coming out cheaper despite the increased price and why would they be angry saving money?
- Honda crv squeaking again. From the back side. Over bumps 98 model? My crv was squeaking bad so I had my camper bushings replaced last year and the noise stopped. Now all of the sudden it started making the same squeak over bumps again only after a year. The garage guy told me to lubercate them. Considering my car isn't low to the ground can't I just crawl under and spray the lubercant without lifting the car up?
- Why does my 94 honda civic over heat but the oil light comes on there's no leaks any where? My radiator over heats the hoes swells but there's no leaks no smoke coming from anywhere the water in the radiator bubbles up when I take the cap off I even put some stuff in it to help cool it down didn't work. I checked the oil looks fine no werid color to it at all. Its no really over heating the engine is hotter then what its suppose to be
- POSSIBILITY OF OVER CHARGING MY AC? I HAVE A HONDA CIVIC EX 04 I ADDED SOME R-134A BUT WHEN I HAVE MY AC ON THE CAR SEEMS TO WANNA DIE COULD THIS HAVE SOMETHING TO DO WITH THIS WASN't DOING IT BEFOR?
