I had Roberts installed x4 new tires on my 91 LS400. Considering age of the car, I took the lowest one. I also took words of Silvia. She has not received any complaints for these tires. At Roberts you don't just take your car in. They'll also check few other things and make recommendation at no charge. They found rear brake pads needs to be replaced, and sure enough they had to be replaced. And, shop itself is getting better in its looks everytime I go there.
