The shorter sidewalls aren't as flexible as the taller ones on high profile tyres, which means the car doesn't roll and bounce about quite as much. This boosts grip and the effectiveness of the suspension at keeping the car stable in corners.
This can have beneficial effects for a car's performance, as extra grip means a car can go around a corner faster, but the downside to this will be a firmer ride over bumps. The tyre sidewall acts as part of the car's suspension, and if there is less sidewall and a smaller cushion of air to absorb bumps, these shocks will transmit through the wheels and suspension to the cabin, making for a more uncomfortable ride for passengers.
In recent years, some car makers have designed their cars to be more comfortable on large diameter wheels as standard, although that is unlikely to be the case when fitting aftermarket wheels and tyres to a vehicle. The question is whether you can put up with this extra firmness for the added grip and roadholding the tyres will provide. If you're increasing tyre size by an inch, it might not have a big effect on soaking up bumps, but if you're increasing size by two or three inches, then you're likely to notice the difference.
And if the bumps are severe - especially crashing into potholes - then there's a greater risk of either the tyre or wheel suffering damage as a result, as a low-profile tyre doesn't have as much ability to absorb the impact as a standard tyre. Another negative of low-profile tyres is their higher cost. While the lower profile means there's less rubber to start with, these tyres tend to be designed with performance in mind, so they usually have more advanced construction so that they perform at their best.
Of course, low-profile tyres need larger diameter wheels, and simply buying a set of these to fit them on will add to the expense. What do you think of low profile tyres?

Low profile tyres have thicker shoulders and steel belts to give them more stiffness and stability. The majority of low profile tyres have rim protectors to protect the edges of the alloy wheels. Low profile tyres have more contact with the road and stability due to larger tread widths, which make these very popular, however, more contact with the road will make low profile tyres wear out faster.
Driving styles also wear tyres out more quickly especially if you corner at high speeds and brake hard. Be very careful when driving over speed bumps with low profile tyres as cars with these tyres often have lower suspensions too. Hitting a pothole with low profile tyres can cause serious damage. Regular maintenance is key to getting the best out of low profile tyres.
As well as the tyre size on the sidewall there will also be a number and letter at the end of the tyre size to indicate the load index and speed rating. Many performance cars come with low profile tyres and a suspension system to compliment them which helps to improve the tyres durability and longevity. If you are thinking about changing to low profile tyres, you will also need to change your wheel size and modify your suspension to complement them. Whether you have low profile tyres or regular tyres tyre maintenance is very important, so you need to check general condition, tread depths and tyres pressures regularly.
