I wish to change the rims on my Coromal Pioneer XC van (tandem axle) from 5 stud (100 series L/C) to 6 stud (80 series L/C) to make them compatible with my tow vehicle. What is involved, and NOT counting new rims and rubber, would it be very costly to alter?

Thanks Nick

Probably just changing the brake drums. New bearings would be advisable at the same time.

Should be a simple matter of swapping hubs/drums (assuming it has electric drum brakes?) from (LC) 5 to 6 stud.. Alko do both..
(you'd need to ensure that you specify the same bearings that are in the existing hubs)...
wheel off-set may be an issue??

Changing hubs can often come down to just a bearing change. It is common to find many bearings with the same inside diameter but a variety of outside diameters and vice versa.

Before you do anything, I would start by asking Coromal. Your van may come with a variety of hubs and stud patterns to suit different tow vehicles. They can tell you what has to be done.

If they can't help then try a caravan dealer that has a workshop that carries out major repairs and alterations. Chances are they have already done this conversion.

If that fails then you will have to do a lot of accurate measuring of hubs, brakes, wheel back spacing etc. plus checking bearing numbers and discussing them with a bearing service. I have done things like that while building modifed two wheel drive cars. It is not hard but I would imagine it would look like a daunting task if you are not experienced.

Another possibility might be changing the stud pattern on your existing hubs and brakes. Give this company a ring.http://www.hoppers.com.au/ They will be able to do the job without any problems. If the van has to be taken to them then it could be a problem if you are too far away but many conversions can be done by mail so see what they say.

It is also possible that your hubs were supplied blank, i.e no studs, by a company like Disc Brake Austrailia. This is a common thing and people like custom car builders and possibly van manufacturers have them drilled to whatever stud pattern they want.

Check with Coromal, DBA or Hoppers. If that is the case then the conversion will be easy.

Thanks everyone for your replies and advice.
I think I will start by contacting Coromal and work from there.
As Splits said they may purchase blank rims and drill the stud pattern required, if so this could make the change I want pretty easy. Thanks to all who have replied.

I recently went through a similar excercise.

Apart from the stud pattern, the thing you need to watch is the offset. From memory, depending on your LC 100, it will probably be positive 60m offset ( P60), I think the 80 series is -ve 12 or similar. This is the distance from the center of the wheel to the surface where the wheel mounts.

A 0 offset means the wheel is centered on the center line, positive means the center line of the wheel is closer to the center of the vehicle than the mounting surface and visa versa.

This all means that apart from the number of studs, you MAY have to move the axels in or out. It will depend on how much space you have between the side of the tyre and a) the inside clearance and b) the outside clearance.

I hope this make sense.
Also check the studs are corrent, they are different between the two vehicles.
