18" wheels

[jocko]

are there any 18" wheels that will fit on my van, or will they need adapters. Have been told this size would be best to help bring down the revs on my TDI engine, with petrol gearbox. Want to fit 245/55/18 tyres.

you dont need to go 18 inch for that. just up the sidewall ratio a bit. ie 65 or something.
look for a tyre size chart

With 18s and big tyres watch the edge of the swing arm

So will 195/65/14 be ok and am I ok changing just rear, or all 4. Cheers

use this

compare the standard 185 / 82 / 14 tyre with the one you require

you dont need to go to 18 inch to get a bigger diammeter , in fact there are many 18 inch tyres that sit lower than the 14 van tyre!

you can change just the rears no probs.

also if you google tyre speed calculator and know your gearbox code you can figure out what revs the engine will be doing in each gear at different speeds.

May I suggest you don't ask the same person for anymore advice!

They're 45mm smaller than the standard tyre.

195R14C's are 21mm larger.
205/80/14C's are 30mm larger.
205/82/14C's are 38mm larger.

I also have this size but all round, they are 5% larger than standard.

Perfect for my ADY conversion (seen a GPS 170 kph)

I didn't, someone posted on another forum, that they had put those size on with their TDI conversion.

can I ask what wheels you both are using?

[Titus A Duxass]

I'm using Merc ML wheels with 20 mm spacers/ adaptors.
