Car is a 2003 Honda Accord, so quite an old wreck 
I noticed a few weeks ago that I get a serious case of the judders at around 60mph but only when accelerating, get to 60mph and take my foot off the accelerator and the judder stops or certainly goes down a level where I can't feel it. Passengers in the car can also feel the judder so not just being transmitted through the steering wheel which only the driver can feel.
Had 2 new rear tyres fitted just on Friday and had the fronts rebalanced and the wheels laser aligned as I thought that would resolve the judder.
So what else could be causing the issue, I could take it back to the tyre place and get them to recheck as they stated a months warranty.
