Tyre sizes

[Bass Junky]

Hey guys,

I have the option of buying some tyres at an obscene price at the moment.

Problem is this.....

I have 8 inch rims on the front and 9 on the back (Buddy Club P1)

The front tyres are fine at 235/45/17

The rears have the same now, but I want fats for the back at 255/40/17

the tyres I have offered to me are 245/45/17

How is this going to effect things........

Is there going to be a heap of difference between running 245/45 to 255/40 in regard to speedo calibration and all that.

Thanks for any help

it will give you an idea of how far out your speedo will be changing tyre sizes..

How obscene is obscene?

Was going to cost me $1000 for a set, now about $480

just out of interest, what offset are your current buddy club rims? front and rear?

Not exactly sure to tell you the truth.

45 Profile on a 245 is quite big, Id try and get a smaller profile to reduce sidewall size a little.
