hi RogEnfield

These should be fine as long as you dont overload the car. No matter what the size of the tyre the load rating will be equivalant to the size of the tyre.]

I think the vectra estate with nice wheels is quite nice, I do think however that is the wrong engine to go for,its going to really hurt fuel wise and tax etc. Maybe look at diesel power if doing long distances, I dont think you will see better than mid 20's fuel wise with that engine. Re the wheel size, shouldnt be much of a problem except the ride will be quite firm and tyres will be expensive

Finally my last car had 18's on it and after 60k a crack was found in the back left alloy wheel puncturing the tyre and needing a entire new alloy and tyre. The roads around where I live aren't great but still it was an expensive repair...just saying if you travel on bad roads often.

Goold luck mate

I changed the wheels on my car 17" to 16" - if you do change wheels size consider whether the car's speedo will need to be adjusted, and don't foget to discuss with insurance company.

So why did I change ... the price of 215/50/17 tyres is so expensive, after allowing for the cost of the new wheels, I still still saved money at the point of fitting a second set of tyres. I changed to manufacturer standard 205/60/16 - still not the cheapest tyre size but that is worthy of a different discussion thread all together.
