Name of Wheel Parts

elem_local_t_know_sketch01.gif

Wheel Size

elem_local_t_know_sketch02.gif

Offset

elem_local_t_know_sketch03.gif

The offset indicates the distance from the center of the rim to the attaching disk part (unit:m/m). As seen in the attached drawing, the offset is indicated by "+" when the fitting surface extends beyond the central line of the rim and "-" when it is falls within. Caution is required to prevent the tire from coming into contact with the fender of the vehicle or the brake caliper if the offsets are very different.

P.C.D.

elem_local_t_know_sketch04.gif

The number of bolts used to install a wheel varies from 4 to 6 depending on the vehicle model (except for some vehicle type), thus the wheel to be installed should also possess the same number of hub bolt holes. P.C.D. stands for pitch circle diameter, and indicates the diameter of the circle in mm connecting the center of each hub bolt. Since the P.C.D. also varies according to the vehicle model, make sure a suitable one is selected.

Clearance

elem_local_t_know_sketch05.gif

Fender clearance indicates the marginal space between the tire and the fender or body of the vehicle. Inner clearance indicates the distance between the tire and wheel and the body part which is positioned closest to the tire and wheel. Dimensions for both right and left clearance should be measured on a level surface, and the smaller value is then considered as the inner clearance.

2-Aspect ratio

4-Rim diameter

5-Load index

Tread depth and tread wear indicators

For the most part, motoring law in most countries determines that your tyres need a minimum tread depth to be legal. This varies from country to country but is normally around 1.6mm. To assist you in figuring out when you're getting close to that value, most tyres have tread wear indicators built into them. If you look around the tread carefully, at some point you'll see a bar of rubber which goes across the tread and isn't part of the regular pattern (see the picture here for an example). This is the wear indicator. It's really basic, but it's also pretty foolproof. The tread wear indicator is moulded into the rubber at a depth of about 2mm normally. As the rubber in your tyres wears away due to everyday use, the tread wears down. At some point, the tyre tread will become flush with the wear indicator (which is normally recessed into the tread). At this point you have about 2mm of tread left - in other words it is time to change

Minimum legal tread depth does not mean "safe".

Actually it's wise to change your tyres before you get to the wear indicator, as by this point, the effectiveness of the tyre in the wet is pretty limited, and its grip in the dry won't be as sharp as it was when new. In 2006, Auto Express magazine in the UK did some pretty rigorous testing on "legal" tyres. They are campaigning to have the legal minimum in England increased from 1.6mm up to 3mm. Their reasons are backed up by testing : at 1.6mm, despite still being perfectly legal, the stopping distance is increased by 40% in the wet over tyres that have 3mm of tread left. They performed the test using the same car, under the same conditions with the same driver. The only thing that changed was the tyres. The Fifth Gear TV program performed a graphic demonstration of the problem by equipping two cars with different tyres. The lead car had 3mm of tread left, the trailing car had 1.6mm. The cars were driven at 50mph at a distance of 3 car lengths apart - not safe, but representative of the real-world. When the lead driver performed an emergency stop, the trailing driver reacted nearly instantly, but despite years of training and an ABS-equipped car, he slammed into the lead vehicle still doing 35mph.

DZ101%20200x200%20.jpg

The Direzza DZ101 is made from an ultra-high density silica compound with a reinforced lower sidewall for increased stability and high lateral grip. The latest Digital Rolling Simulation (DRS) technology is used to provide improved wear uniformity and reduced road noise across the life of the tyre. This translates into an outstanding package of longer tyre life and superior handling ability.

Silica based tread compound

Silica provides improved braking, cornering and handling in all conditions and also reduces rolling resistance which can improve fuel economy

Jointless Band construction

Jointless Band Construction (JLB) ensures the tyre retains its optimum shape when cornering for maximum steering response

Directional Tread Design

Outstanding performance characteristics while still effectively dispersing water to reduce aquaplaning

Fuel efficiency benefit

The silica used in the tyre compounds help to reduce rolling resistance which can improve fuel economy

what's the price for 19" 235/35 and 275/35?

DZ101 is a good tyre, adequate for wet and dry. I used this before I changed to Goodyear F1 (German). However, the DZ101 starts to lose grip after 50k and it has caused my ESP to intervene on 3 occasions when I accelerated at a bend, and the tail slipped a bit. I swear the ESP works to bring the tail back, an electronic wizard that must have in a car.

The scratch band on the DZ101 to prevent rim scratch does not work (I scratched mine), don't trust it. Overall, a good enough tyre.

Toyo Proxes T1-R

Features and Benefits

Longer wear life

The newly designed silica compound effectively minimizes heat-build-up, which together with the improved casing profile provide effectively resistance against irregular wear and structural stress, resulting in extended total wear life.

Excellent wet traction performance

The rigid tread hardness delivers excellent ground contact on dry surfaces, whereas the unidirectional tread pattern with V-shaped main grooves and rigid shoulder rib pattern ensures superior water drainage performance, outstanding wet capability and high-speed handling.

Improved riding comfort and breaking performance

Optimal pressure distribution of the tire structure ensures a road-hugging grip even under the most demanding road conditions, while retaining excellent riding comfort and breaking performance under wet and dry conditions

SPORT RIMS

What it's supposed to do:

Improve handling by reducing upsprung weight and allowing the fitment of wider tyres. It's safe to say that the majority of alloy rims are brought for their style rather than their function. Still, there are many benefits in putting on a set of lightweight wheels/rims to replace the steel or alloy ones that came with the car. Forged rims are extremely light and they allow the car suspension to do its work more effectively, thus improving both steering response n ride comfort. With Technological advances, low profile tyres are becoming less unforgiving in their ride characteristics and they are alos quite cheap these days, so a plus-one upgrade from standard set-up gives noticeable handling improvements with hardly any impact on the comfort.

The 2005 Wheels Tyre Test is published in the May 2005 edition of Wheels magazine, in newsagents now.
