Yeah, wider tires for the 14" rims were also a no-go where I live. 14" rims = econo thin crppy tires.

That's why I kept the stock rims, went 2 cm wider in tyre size (195/60R14) and I'm done for wheels.

But now adding 2.5cm spacers should prove interesting.

 

Depends on what your stock offset is. If its 55 mm then 25 mnm spacers reduce the offset to 30 mm which is prone to rubbing. The greater problem tho is the much greater bearing loads you are having. Premature wheel bearing failure is certain. Especially on the front where caster caused camber increases will have both handling and parts negatives.
If you use spacers try to choose wheels that will keep the inner wheel rim about same distance from hub as original.

 

Yeah, the wheel bearings would suffer...

Actually today I went to pick them up and one of them is banged up pretty badly right where it goes into the hub!!! So I passed on buying them - the seller had neglected to mention that minor detail...

So I'm back to square one.
