I saw on a website that going up from 255/70/16 to 285/75/16 might cause brake problems. is this true. it seems a lot of yall do this with no problem. also, what changes in gas mileage and spedometer accuracy occur with this change? sorry if i'm asking too many questions about tires and wheels, mac

 

I went from 255's to 285's and havn't had any problems. My speedo is off 5 mph at 60 mph.

 

I dont think you should have any probs.

 

thanks yall. wandell, does youe spedo say you are going 65 or 55 when you are going 60?

 

When my speedo says 60mph, I'm actually doing 65mph.

 

can you reset your spedo?

 

Your dealer can recalibrate it or you can do it youself with one of the aftermarket computer tuners like the Superchips or Hypertech.

about how much will that set me back?

 

[QUOTE=bassmaster1061]My dealer charges $100. It might be a good time to buy the Edge. That $100 will go a long way.

 

how much is the edge? what exactly does it do?

 

Edge is another aftermarket computer tuner. It allows you to recalibrate your speedo, change tranny shift points, eliminate top speed restrictions and tune your engine for more power.
