80 Series & Tyre Load Index

just went through all this crap myself went to a tire dealer and they put 109q on when they should of been 110s see i didnt know anything about load speed rating until rohans thread about insurance and stuff.
now with the RTA i rang them and they said it would be fine if you got an engineers ticket but i didnt look that far into it i just rang the tire dealers up and said what they did and they put the correct tires on.
With a road worthy i take it your talking about a pink slip and they only check tread not the load speed rating. Now with insurance they wont cover you if your car is unroadworthy now if you want to take the risk of them not checking your tires go for it but in a ding it takes 2 sec to check the tires and then you placard so i bet your bottom dollar they would. Now how much would you want for your rig $30000 (i dont know just guessing) now to get the proper tires it might not cost anything more or maybe $10/tire =$40 thats if they come in that size not to sure but its well and truelly worth it considering insurance companies would no doubt look at getting out of paying anyway they can and that would be one way.
personally i wouldnt risk it. but at the same time and engineer might ok it then you might have to check with your insurance company.

gday john.
vic laws state that the minimum load rating on your vehicle placard is the minimum you can fit.end of story.i just had a huge blue with another tyre place up here about load ratings on cars.he was wrong lol.
and as said above insurance null and void if wrong tyres on.
new job coming so no fraser this time:-((

Glenn, just to be a pain in the arse, have you informed your insurance company that you have changed wheel types, given that you quote a 31/10.5x15 means you must be running 8" or 7" white spokers, which were not standard fare in the first place?

Just went through this myself. I bought the car with some crappy korean or something 31 x 10.5 x 15 on it and one gave up and bubled out after apparently 35 - 40k. Looked around and found only a couple of 265 / 70 15's that had the load rating. I couldn't find and 31's that were up to the task. A couple of tyre blokes here in Bris said straight away that I had the wrong tyres and they would not recommed ggoing back to the 31's as insurance will not cover.

I looked around for a long time and finally put 16 inch wheels on and got cooper discoverer ST's and they are great. There are more tyres to choose from in this size however some are more expensive. The vast majority though are up to the load rating.

Toyota must have had deal going with Dunlop when they originally put the 15 x 7 chrome wheels on because there are very few metric tyres or imerial tyres around that will do the job. Not even BFG allterains all the way up to 12.5 x 33 are up to the task on the 80 series.

Anyway got the new wheels and they are nice and shiny aswell so I am happy.

Good luck,
Charlie
