Best tyres for 3MPS's

[Nexus]

Hi guys.
I went to my local Bridgestone dealer for a quote on the Adrenalins and he refused to fit them as they don't come in 215/45/18, he said you car is not road worthy so if you have a accident the insureance company may not pay up.

Some of the southern states are starting to enforce new mod laws????
I think you may be supposed to get a mod plate engineering certification for any alternative tyre fitment.

QLD might be going the same direction.
Haven't seen any confirmation of that yet.

We can thank all the people who fit tyres without proper regard for the guidelines for that. Unfortunately, there's quite a lot.

Do u mean the tyre shop would not let you put 225/40 (45?) on your standard MPS rims. Is that beause they are 7" wide or because the car comes standard with 215/45's ??

Thats right, theres no 215, which is why my Bridgestone service centre said go the 225/40's. The Wynnum Bridgestone said nothing about insurance, and he also said he'd done quite a few Maz 3 MPS's with these.

I doubt your insurance co will be looking at tire size. They are more than likely just to check the load / speed rating of the tires only. The physical size surely wouldnt matter unless its outside of the wheel arches and/or clashing with the body work, or has no tread..

Also, i've never heard of an insurance co not paying up over tire size...

If they aren't putting the kibosh on alternative fitments (need a mod plate), then it would likely be because of the 225/40 on 7" issue.

If this is the case, then I reckon around 75% of the population are in trouble. Most people opt for a wider tire on the 1st change. I know I did, and the Bridgestone Service centre I went to had no issues with it (infact they recommended the 225/40 on the 7" standard MPS rim)

There's nothing to say they're doing this in QLD yet, but I have had one service agent suggest it's coming, and another say they've been expecting it.

That was my comment too. Anyone with an aftermarket wheel would immediately be unroadworthy under the supposed new rules until they get an engineering check done and a mod plate fitted (probably specifying tyre size also)

I have my doubts it will happen in the short term, as so many owners would be outside the rules with fitments that didn't have a problem under the previous rules.

I've heard the legislation is there down south, but I've also heard that it isn't being enforced. If it happenns it will probably be part of the national road rules push.

I support the idea, although it will be a pain in the bum if it affects me as I'll have new rims fitted in two to three weeks (they landed this morning - yay). Thing is there's a lot of people who've fitted rims and/or tyres that are really marginal and although it's nitpicking, probably shouldn't have them fitted. To top it off, a lot of service agents don't do every single check, and rely on a generic table of fitments that seems to be misleading for the 225/40R18 size.

By putting an engineering requirement in, that responsibility is passed to the engineering inspector and not the owners (or lazy service agents) who can be expected to stretch the rules when it suits them.

Bridgestone says a 225 is legal and roadworthy on a 7" rim in Queensland, so Bridgstone dealers shouldn't refuse to fit them, if not sure they should check with the tyre manufacturer and of course state laws.

The issue is 40 vs 45 profile, not the 225 width. 45 profile OK, 40 not (For most manufacturers) needs to be checked on an individual basis. If 225/40R18 on 18x7 is OK'd by the manufacturer...no worries, but not many are. I've seen three. Federal SS595, a BF Goodrich, and one other that I can't recall.

The federals are a good example - of the published specs for three different types of SS595 - standard, EVO, and RS, only the standard SS595 is OK'd for 225/40R18 on 18x7

Hi.
The local bridgestone Dealer I went to, got his bible out , and that's when he said he would not fit 225/40/18 and his words were the car would not be roadworthy.
I am not saying he right or wrong just quoting what he said, on the other hand it could have been he wanted me to buy the 050a 215/45/18 @ $430 each.

Three cheers for service agents who do their job properly.
