They are called Tyre Safety Centre and are also known as Alloy Wheels Northern Ireland.

Well, hopefully the new wheels they send you are straight... but why did they use 2 brands in the first place?

They only had the fronts in stock and had to order in the rears.

Yes. I would insist on the same brand for all 4 or get money back on the entire order. If they didn't say hubcentric rings were needed, I'd also insist on 4 that don't require it and I'd inspect all wheels very closely before I spent any money to have tires mounted. I don't know about this parts supplier, but my experience with parts ranges from horrible to good. Many guys will say stuff just to make the sale and have no real knowledge or hide certain facts. Sometimes asking a few additional questions is important and getting a less than 100% correct answer can be a red flag.

Im suspecting that it could be down to the quality of the replica rim. It does not fit as tight on the hub as the 19" OEM I took off. Although they dont need hubcentric rings there is defo a tiny amount of play on the hub. Probably down to manufacturing tolerances not being as good as OEM.
The rear rims they supplied are a different brand and require hubcentric rings. I wasnt happy about this originally but thought if they drive ok Ill accept it. Shoud I ask for the same brand fronts as rears?

That is alot of weights on a wheel.

I have just a bit on my 22''s, on my 20''s I hardly had any weights. All replica wheels.

Keep us posted on the outcome..

Guys Im running my OEM 19's on the front and the replica 20's on the rear. The 19's have a slightly larger diameter. Is ok to run with this set up? Im concerned about causing some possible damage as Im sure Ive read somewhere that its bad to run different size wheels.

Theoretically the tires should have the same (or very close) diameter and you should be fine IMO until your replica situation is resolved.
I wouldn't take her on the track or anything.

Either the wheel or tire is very bad, and if new would be a parts warranty issue from the supplier.

What you NEED to do is have the wheels in question measured for out of round by a good tire shop with a road force balancer which will tell you which aspect is that far out whether it is a bent wheel, bad tire or the original tire shop improperly mounted/balanced the wheel.

Sorry, just read the whole thread, it seems you have 2 problems, 1 is you need the hub-centric rings. 2 is the bad balance issue.

This is all true. Some funky wheels causing a problem compounded by a balancer guy who probably is over his head (or maybe would get fired if he told you the truth). A decent, round wheel with non-defective tires can be perfectly balanced with very few weights.

The wheels look great though. Too bad there is a problem.

What is the difference in diameter of the tire? There is some tolerance for difference diameter size but not much. Once past that amount the vehicle computer will think the smaller diameter tire is spinning because it has a higher number of revolutions vs. the other set and it will try to compensate mechanically. This could cause some premature wear or worse over longer distances because you are on dry pavement. Someone here will know what an allowable delta in diameter tire size.

You have an 05 so you have the x-drive transfer case. It has "tire tolerance logic" and when it sees slight difference in wheel diameters it lets some pressure off of the clutches to prevent premature clutch failure in the t-case. Of course I wouldn't recommend it for very long, and not if there is a big difference... but for a slight difference for a short period of time it will be fine.
