I’m looking at a set of wheels in 15inch 5.5 for my T25 and need advice on tyre size for not rubbing and also to look right. I gather I’m looking for 175 or 185s but it’s the ratio I’m not sure on. That’s the depth of the tyre from the rim. Please could someone advise what they have found works. Also if from the info below you can tell of if I will need spacers.
Thanks in advance

Which engine does your T25 has ?
Which transmission?
Is it heavy or light ?

I recently fitted my Caravelle with a set of 215/75R15 on 5.5 x 15" ET 30 wheels.

Looks and drives very well.
2.1 DJ engine, 5 speed transmission, factory fitted AC always working when driving and stock suspension.
I weight the van 2 weeks ago, and the empty weight is 1550 kg.
