Technical Rim Question

I'm sure that there are many mates here which can shortly explain the advantages and disadvantages between modular and conventional rims.

All the tire "specialists" here (Ireland) had no decent answers.

I gave up after somebody told me ("Tire Specialists" written on the sign at the shop): " ..ehhr the modulars are for racing"

No real advantage or disadvantage other than ease of construction, and or if you need to replace a rim or change the offset, you only need to buy a new part rather than a complete wheel. however they are usually more expensive than non split rims so this has little advantage!

It depends what you mean by 'modular', because the modulars that are fitted to 4x4's usually aren't. Modular that is.

True modular wheels are made up from two or three pieces, the rim(s) and the centre. They are usually bolted together with lots of little allen bolts. The common 4x4 'modular' is just a welded steel wheel with lots of little plastic fake bolt heads stuck to it.

What they said ^^^

Most "modulars" are fakes so the advantages come down to two things - appearance and offset - if you view either as a benefit or disadvantage to what you want, then that should be the basis for making the choice. Offset is usually greater than factory rims so the wheels stick out more, arguably the wheels look better but the flip side is that the cheap aftermarket wheels (modulars, 8 spokes etc) usually start rusting before you finish fitting tyres to them so they don't look good for very long! A set of silver modulars looks quite smart when new though, I've got silver modulars on my 110 sometimes and I much prefer them to most others.

Thanks for the replies so far.

I got this now for 4x4 modulars (mostly fake and no significant benefit), but what is the principal idea behind it in general.

I was thinking about better stress distribution during differential temperature related expansion or something like that.

If there was no benefit and the modulars are just more expensive, the rim manufactorers must have the best salesmen in the world.

A pseudo modular for a 4x4 generally has different offset to a standard rim and can be bought in a greater variety of rim widths and offsets than a OEM rim.

A real Modular or split rim offers an even larger variety of sizes and can be custom built by yourself. Also if you dented a rim edge you can replace just that inner or outer rim without the cost of scrapping a whole wheel.

Wolf rims look better than pretend modulars, will be stronger and can be bought (new take off) for similar money!

I paid £30 + VAT each recently for a set of 5.

They were painted white, so a quick rub down and they will be silver grey soon.

The modular rims are generally alloy. 'Steel modulars' is just a joke.

The advantages of modular alloy rims:

- the sytem provides a higher level of customization (colors, offsets, PCDs etc) at lower costs

- the centers/spokes can be forged (forged alloy is 2-3 times stronger than cast alloy) which leads to a stronger (or lighter) wheel.
