1993 1.9 Which wheels fit my 405? - Neil34

I want to put some new wheels on my 405 but I'm a total beginner when it comes to sizes etc.... I have a 1993 SRDT. The existing tyres say 185/65/R14.

My questions are :
1. What do each of those figures actually mean?
2. Does this mean that my wheels are also size 185/65/R14?
3. Do some dealers use a different way of measuring that is 'equivalent' to 185/65/14?
4. Could i put 15's on if i wanted? Does it change the handling and how?
5. Can i put wider wheels on? and how...what would i need to change?

Thanx in advance, Neil.

185 means 185mm wide, 65 means your side walls are 65% of the width (185mm) high and 14 means wheels (not tyres) are 14 inch in diameter
2. Does this mean that my wheels are also size 185/65/R14?


It means your wheels are 14 inch in diameter
3. Do some dealers use a different way of measuring that is 'equivalent' to 185/65/14?


No AFAIK
4. Could i put 15's on if i wanted? Does it change the handling and
how?


Yes, yes but you will need to tell your insurance. It will also make your speedo read wrong
5. Can i put wider wheels on? and how...what would i need to change?


Yes as above
Thanx in advance Neil.
