This is at 110 km/h (not miles :shock: ) cruising out the highway after putting on the 245's. Before the lift and tires, it reved about 1600-1800 range. I should get the computer recalibrated to get my speedo corrected.

We're you actually cruising at the speed in the picture...:shock:

With my new tires my speedo is off 1 MPH when compared to my GPS speedo.

EDIT: LOL, I thought the speedo was in MPH lol :oops:

I'm not sure about getting everything recalibrated, the engine is prolly just revving higher due to the bigger/heavier tire and wheel combination...I've noticed this a little bit as well. Wouldn't be too worried about it.

Yeah I was just running down the highway. It does tach higher now, but I'm not sure how fast I am going. It can't be too far off, just curious though.

It is only a v6 8)

A guy did pass me on a CBR900RR andI think he was doing well over 110 MPH. I wish I could have traded for the afternoon. :twisted:

I was confused too... I thought that was in MPH...

In my case, my speedo went from 1 or 2 over to 1 or 2 under (depending on the speed)

at 73/74 I am running 2000 RPM, you should run less RPMs with larger tires of course you maybe running 2/3 miles per hour faster now and dont know it!

I had my speedo check a few time by thoes road speed sighns. I also had my cousin who is a NY state trooper paint me and I was EXACT. Not 1 mile over or under and he just had his laser gun CAL a few days ago.

At first I was about 2 mph under what the sighn said. But now When it says I am doing 55, My speedo matches and also my rpms are the same after I lifted it.
