Tire Width

Tire Width
I am building a custom frame for my 67 chevelle. I want to increase the frt tire width (wide track) which would make the frt 2" (centre - centre) than the rear. I am wondering if this is acceptable. I dont want to widen the rear diff & order custom axles. I think the rear must be wider than the frt ( no real reason just always thought it was). I would appreciate some info & input.

so you're using the same tyres, but just increasing the track width?

No Im installing 18" tires with a stock offset. And yes i want to increase track width ( 1" per side )

I'm being serious.... you're putting 18" wide tyres on the front?
What's the reasoning behind the extra inch track width?

Ok its a slow night up here in Canada, so I'll bite. No the tires are not 18" wide they are 18" rims (in diameter) the tires are 245's. So that would read 245/45X18. I hope that clears up this confusion. Most people know when someone say's they are running 18's they mean rim diameter.

so my question still stands ... the tyre width is the same or different?
what i'm getting at is that a track width increase of 2" may mean the outside-outside width of your tyres is increased by a bit more than 2"

If you want to increase track 1" per side just subtract 25.4 from your offset. Provided these are the same width wheels. Done.
