6J wheel width ?

Post by **dunketh** » Thu Aug 30, 2007 3:02 pm

Hi, I'm looking at some alloy wheels which are 14" x 6J for the mog.

Does anyone know what 6J translates to in numbers?

I'm already running 155 tyres and it'd be nice to fit these to the new wheels but I don't want them silly-stretched like the euro VW chaps!

cheers

I have 6J's on my cavalier and that runs either 185 or 195 tyres. HTH.

6J means that the rim width is 6 inches. J I think relates to the shape of the wheel section.
Ideal tyre width would be 185 - 205 - 155's will give you the 'euro' look.

6" wheels will put quite a strain on your wheel bearings - and you would need 185 tyres. Are they correct pcd (ie 4") for Minor ? With the wide tyres - the steering may be quite heavy at low speed!

They're early Manta wheels. I believe the PCD is correct but am still not sure about center bore or even width. I'm assuming (yes I know

) that the offset will be fine given they're from a RWD car.

I'm not sure about the whole bearnig argument. Minor bearings are pretty beefy when compared to several other cars I've had. Though point taken its all about where the center of the load is.

I don't know how true it is, but I've heard the single rear bearing allows for a fair bit of flex and load on the halfshafts which can be a major factor in snapping them. Certainly a few Midgety people reckon that's the case, and a twin bearing mod is available.

I reckon moving the load around might not help bearing life, but then neither would adding more lateral grip (and making use of it)! Worst case is slightly shorter bearing life, which might be a good excuse to move over to roller bearings anyway (which can be nipped up a bit when too much play develops)

I ran 6's for years on my minor with no ill effects whatsoever. However, I don't think manta wheels are 4 inch pcd.

Viva's used to be 4" pcd - I had 12" wheels on my Mini before anyone else!!

I know vauxhall used to run 4" PCD and I've heard that early mantas are different to later ones so I'm hoping they share the 4" as using on Firenzas, Vivas etc..
Oddly my mates chevette does not use 4" PCD despite being ancient.

Mantas (from the land of the metric) weren't Vauxhalls, hence I think they are 100mm pcd - same as chevette .
I'm sure my friend had to adapt his hubs to suit back in the good old days when they were current.
Should be easy enough to find out.

Aye - plenty 13" wheels at 4" pcd - very few bigger diameter. And you MUST NOT try to make 100mm wheels fit - they won't!
