Tyre Load Advice
Have just been to have 2 x front tyres fitted I had rung the fitter up earlier for a quote which I agreed, he had asked me what load rating they where first.
So had to go out to car to check, I looked at one of the rear one's that where only fitted 3 weks ago (elsewhere) showing (H) My car is a 2005 Avant 2.4.
So got to garage & the guy said he would'nt fit H as they should be W rating?
the same as the two Pirelli I want replacing on the front.
He also said that the other the other tyre fitters should not of put them on
mine as illegal & could make my insurance void?
Before I get onto garage is this the right advice please.
Thanks

I think the letters you refer to are speed ratings (at least in the US). The following info is from an online tire web site. The OEM tires may be W rated. Can you use an H rated tire if you dont plan on driving over 210 kmh. I guess you would have to ask an expert that question.

Beginning in 1991, the speed symbol denoting a fixed maximum speed capability of new tires must be shown only in the speed rating portion of the tire's service description, such as 225/50R16 89S. The most common tire speed rating symbols, maximum speeds and typical applications are shown below:
S 112 mph 180 km/h Family Sedans & Vans
T 118 mph 190 km/h Family Sedans & Vans
U 124 mph 200 km/h
H 130 mph 210 km/h Sport Sedans & Coupes
V 149 mph 240 km/h Sport Sedans, Coupes & Sports Cars
When Z-speed rated tires were first introduced, they were thought to reflect the highest tire speed rating that would ever be required, in excess of 240 km/h or 149 mph. While Z-speed rated tires are capable of speeds in excess of 149 mph, how far above 149 mph was not identified. That ultimately caused the automotive industry to add W- and Y-speed ratings to identify the tires that meet the needs of new vehicles that have extremely high top-speed capabilities.
W 168 mph 270 km/h Exotic Sports Cars
Y 186 mph 300 km/h Exotic Sports Cars
Load Index
P195/60R15 87S - The load index (87) is the tire size's assigned numerical value used to compare relative load carrying capabilities. In the case of our example the 87 identifies the tires ability to carry approximately 1,201 pounds.
The higher the tire's load index number, the greater its load carrying capacity.
89 = 1,279 pounds
88 = 1,235 pounds
87 = 1,201 pounds
86 = 1,168 pounds
85 = 1,135 pounds
