Tyre load ratings?

Hi Guys,
 
With my Works on the way, i am ringing around trying to find some tyres.
 
I have two issues arising, firstly that many places can't/won't do stretch. and secondly all are concerned about load ratings and will have to 'do their research'.
 
so far i have 3 places (i think the only 3 in perth) that can stretch off doing their research for me but they're pretty much too busy to do it for me (been a week or so an none gotten back to me).
 
My question is, i am looking at 225/35 on 9" (perhaps 235/35 if it can fit clearance wise) and 245/35 on 10". 
 
The stock tyres have a load rating of 94V and i would like to keep this rating since i drive the car daily at around 100km/h to and from work.
 
My question is, what tyres are people running and what load rating do they have?
 
if someone can at least point me in the right direction i can then pass on the information to the tyre places and try to get things moving. At present i have NO IDEA what tyres are going to cost me! but it is looking like more than the rims themselves!
 
cheers
Ant

Not sure many people really look at the load rating around here. I just got whatever will fit.
 
Also, i'm surprised you found ANYWHERE that would offer to stretch tyres over the phone. Its just plain illegal in Australia (tyres have maximum rim width ratings; anything more than that is  a no-no).
 
Whenever i go to get tyres put on my wheels i put stockies on and bring the wheels with me. That way the tyre shop has no liability and they are more likely to help you stretch.
 
 
Didnt you have stretched tyres on the Silvia??

Every tire manufacturer's website has charts with the tires' load ratings.

94 is easy to hit though.

Load rating goes out the window when you're stretching anyways.

I had a Falken Tire seminar that touched on proper tire inflation and load ratings. I don't remember a thing of it, but the roast pork was delicious.

Dom - yeah i had well stretched tyres on the silvia, 225/35 on 9.5 & 235/40 on 10.5 but it wasnt my daily. also load ratings dont even seem to get a mention on those cars i guess cause they are lighter. I do have that particular shop looking in to it for me, although they like to stretch Federals (cause theyre easy i guess) and federals in these sizes are only 84 load rating.
 
But as far as getting places to do it, i just take the rims to them loose and they fit the tyres to them and that is end of transaction! they wont fit them to the car or anything like that.
 
firelizard - yeah i did check a number of websites, the only ones that come close that i have found have been Nankang & Nexen in the reasonabley priced brands, they have 235/35 (91Y) and 245/35 (93Y). so theyre both higher speed rated than stock but not quite there on load rating.
 
i guess you're right that load ratings go out the window when stretching but i would have thought a better load rating just would have meant it would respond possibly better when stretched because it isnt at its maximum for load

Here you go..

that rating is PER tire.

^ thanks for that, i had found one on an australian tyre dealer website but it wasnt as comprehensive as that.
 
After doing the maths on the nankangs (91Y Fr 93Y Rr) it works out at a load rating overall average of 2530kg. My car's kerb weight is 1680kg. So thats 850kg over so even with a full car load (never have that) of 100kg/person that still leaves 350kg.
 
i am going to hve a chat to a tyre joint a week saturday so ill see what they think.

hey Ant let me know how this goes because i'm looking at new tyres and i can only get 235/35in a 91y but the 245/40's are 98y

What happens with load ratings is that you can increase the PSI to make up for a slightly lower load rating.

That's why there's a "Max. PSI" somewhere on the tire. As I recall that is the absolute maximum  that tire can hold safely, so you can bump the pressure a little bit past normal to make up for a lower load rating. Basically it's a safety overkill to allow you to do that safely.

I had a chart that showed how pressure correlates to increases in theoretical load ratings but it's at the store.

Any realdeal tire shop ought to have one as well though, and be able to explain that part. I'm not too good at explaining it.

i would just like to know if running something with a lower load rating won't make the tire bulge or deform in any way

cellyboy - 235/35 you can only get 91. and 245/35 you get 93. i have this problem cause my car is meant to have 94.
 
but if you do the maths on it, for a 2GS 94 load rated tyres all round works out to a capacity of 2680kg of load. the kerb weight (including all fluids etc to drive but no people) for a 2GS is 1680kg. Therefore they have allowed 1000kg of load capacity on the tyres. So to exceed that would be next to impossible!! if you had 5 people @ 100kg each plus 100kg of luggage still only equals 600kg, meaning 400kg safety left on 94 tyres.
 
i am looking at 91 front 93 rear which works out to around 800kg of load over the kerb weight. Again, plenty in my mind. If you look up something like a HSV Clubsport (sorta like a Pontiac GTO for you guys in the US) it is more of a performance car than the GS and it has factory load rating of 91 all round, and a kerb weight of 1640kg. So it has aruond 800kg of safety from factory. 
 
So i reckon 91 / 93 is fine safety wise as long as you keep nice high pressures in the tyres especially when stretching them. As far as insurance and all that shit goes, thats a different story haha

ant i am actually worried about insurance i'm from aus also i got a 90 celsior but i'm thinking of modding the tyre placard lol
also Ant i might have some 235/35r19 sumitomo's 91y or some 245/40r19 98y sumitomo's up for sale in a  couple of days hit me a pm if your interested

^ cellyboy in that case you will probably need to go less aggressive on offset and run bigger tyres e.g. wider and/or taller such as 40 series and roll your guards more if necessay.

Ant i dont want to go a less aggressive offset lol its on a +24
