R speed rating
Speed rating R allows for speeds up to 106 mph (170 km/h) under optimal conditions. Like Q speed rated tires, R rated tires generally prioritize a particular function or unique performance over maximum speed capability.
Also, Can I use 235 tires instead of 225?
Are 225 and 235 Tires Interchangeable? Yes, they are. However, this is only possible if your car’s rims can accept the larger millimeter.
Moreover, Are P and LT tires interchangeable?
P-metric to LT is acceptable, but never replace original equipment LT tires with P-metric tires due to them having lower load capacity ratings at maximum air pressure. If you drive your truck heavily loaded or pull heavy trailer loads frequently, you should consider replacing your p-metric tire with an LT tire.
Does the P matter in tire size?
Physically, they have about the same dimensions and appear to fit interchangeably, but you will notice a difference in the two- or three-digit number following the size called the load index. The higher the load index, the greater the load-carrying capacity of the tire.
Can I mix V and W rated tyres?
You can invalidate your car insurance by fitting new tyres that have a lower speed rating than the manufacturer’s original fit. … Mixing tyre speed ratings isn’t recommended.
What does 70 mean on a tire?

What is difference between P and LT tires?
An LT tire is built more robustly than a P-Metric tire to handle heavy loads under adverse conditions. Heavier body plies and larger bead bundles allow LT tires to be inflated to higher pressures, thereby increasing the tire’s load capacity. It is the air inside the tire that carries the load.
Does it matter if you have different tires on your car?
Primarily, you should avoid mixing different tire brands and different tread patterns. There are rare exceptions for approved mixed-tire fittings, but in general, manufacturers do not recommend tire mixing at all.
