#59 of 67 Wider tires...good call by krony

Sep 29, 2010 (7:28 pm)

My '06 Limited has 43,000...the original 205/55R16 89T M+S Goodyear Eagle LS's were shot and never had much grip as the compound was rock hard.
 
Went a little wider with 225/50R16 92V SL BSW Goodyear Eagle GT's on my stock rims...same rolling radius as the originals but much better look and grip both in the wet and dry...excited to see how they do in the snow. Goodyear store even matched the $95/tire price of sears.com.

Recently purchased 2006 base model with 55K on it, just had panel damage kind of fixed. Probable cause, the bargain tyres that were newly fitted. My first job was change the tyres, would like nice wheels but budget not so good so staying with steel at present. I had Falkens on a Toyota two door coupe in Australia some time ago and they were fast and sticky and after checking several reviews on Edmunds and some other car sites I went for the Falken ZE912 with nitrogen fill. Got em from Pueblo Service in MacAllen, TX, not the best price but makes the service guys smile and come with warrenty and nitrogen fills for life. Spend extra and do the alignment too!
They are great tyres so far, put on 5000mile in six weeks, nice and quiet with even wear. I had a noticeable increase in noise at about 1600mile on my recent trip and realised it wasnt tyres wearing in it was the change in road composition as I crossed through states from South Texas to Dakota.
I will update as time goes by but these Falkens are good in the noise and grip department, even went well in some snow and ice through Arizona with little noticeable change in road handling. Still be cautious though.

'05 PT Cruiser: We are now in our 29+days of 104 average daily temp...what psi should I be running in my tires?

On every vehicle sold in the US – and I am told this is worldwide, but I have not been able to verify this - there is a sticker – commonly called the tire placard - that lists the original tire size and the proper pressure for that size. The placard is usually located on a doorpost or in the glove box – but sometimes it is located in the trunk or on the fuel filler door.
 
BTW, it doesn't matter who makes the tire or what pressure is listed on the tire's sidewall, if the tire size is the same as the placard, then the pressure listed on placard is also appropriate.
 
Having said that, there are folks who think a few psi more helps - in that it decreases the amount of heat that the tire generates during operation. Heat is the tire killer, so they have na point, but I wouldn't use more than 5 psi above the placard pressure or your handling may change drastically.

Hello There, I tend to disagree with the rating for tyre press given from door posts and generic data. Studying automotive engineering back in the day we were taught to look out for signs of incorrect pressure such as excessive wear on outer edges or excessive wear on centre of tyre. Outer edge wear (providing alignment is good) is typically sign of under inflation while high wear in tyre centre is sign of over inflation. I have tested this theory over the years and found that while inflation as little as 2psi under manufacturers rating will definately wear outer edges you can inflate more than 10psi above the rating and be lucky to get centre wear. That being said I run my tyres about 8psi above over stated most year round but tend to lower to 4psi over when excessive wet to give more traction.
If you have ABS over inflation by these amounts should not be issue but driver style will make some difference. As for temperature try a nitrogen fill to reduce temp due to reduced flex in side wall.

While we can argue about the suitablility of what is listed on the vehicle tire placard, it is clear that the vehicle manufacturer specified that pressure and that there are things beyond tire wear that need to be considered when critiquing that value. However, over-inflating the tire a little is probably not going to harm anything - the operative word being "a little".
 
But there is one part of the post that I want to take issue with:
 
".....As for temperature try a nitrogen fill to reduce temp due to reduced flex in side wall....."
 
Sorry, but all gases behave very smilarly and there have been many studies that prove that nitrogen inflation does not change the heat buildup characteristics of a tire. The myth that there is a difference is all advertising hype.

I came to add my opinions not argue, note the word 'try' and 'manufacturers' spec as for 'spin' molecular size is a real fact and scientifically proven and flex in tyre walls adds to heat build up so naturally hardening up the tyre will decrease this.
A lot of advertisers in the US should be shaken up but I have an open mind as to what other 'perhaps experienced people are saying has worked for them I make the effort to understand there is more than one perspective so take issue with a perceived lack of temperament and shoot the messenger!!

Hi, I have owned an 02 and an 07 PT Cruisers. no air problems. I have managed a tire store and have seen the welds break in the center of the wheels and leak.( I had a 99 Taurus that did this) also on newly installed tires, the tire bead may not seat( seal to the wheel) properly and leaks at the bead.( wheel edge that meets the tire) sometimes the tire valve center becomes loose and leaks air.
hope this helps.
