And, adding to Pat's comment; Keeping the tires (assuming same size tires) as evenly loaded as possible. Cheers. Ramon

Hello, I'll second Greg's comment on OEM durability concerns and I agree with Fabrico's suggestion of using hard plastic covers. In my opinion, if you used something similar to modern dirt bike fork shields, it would be an attractive and elegant solution. Ramon Mendoza

One of the advantages I see is that you have camber gain in roll, as with sla setup, but unlike sla there is no camber gain in squat or heave. Of course, this advantage would be better suited to a high powered application such as a racecar. Ramon

Jason, In this day and age, there is no cost vs. quality issues. If an OEM's specs cannot be reached on budget, the business is given up. There is too much to loose by sacrificing quality. There is also no real danger in using the general market tires available. As tireman9 said, the major...

ccw, Tire tread design is usually an optimization arrived at by compromising several different performance aspects of a tire. There cannot be a single best design for hydroplaning unless other factors are completely ignored. And unless it's a competition tire, this rarely happens. In...

Hello all, First of all, I test tires both objectively (I do most of the objective hydroplaning stuff at our facility) and subjectively for a living and have some insight to add. Most of this is from first hand knowledge. Some is from consulting with tire building (as opposed to tire testing)...

There is also the very real effect of steering feel to be considered. Forward mounted calipers tend to add to the steering force felt by the driver while rear mounted ones tend to lower the steering torque feel. This is simply due to the moment imparted by the caliper's mass center (and all the...

Guys, Thanks for the continued posts. Like I said, I can always use more of these types of contacts. Ramon

Phil, I'm afraid you'll be in for a long search if you want specifics on tire content. Information such as compounds, curing procedures and most construction specs (other than what is offered on retail literature) is impossible to get for the end user. The same goes for what is commonly...

Hello all, I’m a little late to this thread but since I just found it, I’ll add my two cents. Regarding passenger vehicle tire testing, there is significantly more testing going on than what has been posted above. Besides the basic government standard tests (BTW, these are about to become much...

Matthew, Thanks for the lead. I never know when something like this might come in handy later. For anyone else interested in the wheels I ended up getting, here is further information. Colorado Custom wheels had a very rapid turn around time and were inexpensive. However, the wheels are...

Thanks Jen, I did have contact with Alcoa regarding this. They are capable of handling the project but the cost would have been several orders of magnitude more than what we had budgeted and what we'll end up spending elsewhere for this type of wheel. Regards Ramon

Roll axis gradient and any gradient change relative to roll. Related to caster and caster trail would be pin lead/trail. What about desired Ackerman percentage/change, steering ratios and so on. Ramon Mendoza

Thanks for the contacts Pat. I had not tried Oz in Au. I had only called their distributor here in the states. Maybe next time I'll try the source first. For anyone interested, I found two places in the US that would work with me on custom widths, diameters, offsets, etc.; Colorado Custom...

Hello Pat, Thanks for replying. I could use contact info for Simmonds. Oz could not help me. Apparently the problem is that most custom wheel makers buy their rims from someone else and 17x7.5 rims or rim halves are not made for a 3/4 ton application that they know of. Ideally, I'd like to get...

Hello, I've been looking for this for days now with no success. I need to either buy or have 4 sets of these wheels made; 17x7.5 28mm offset 8x6.5 bolt pattern. And I also need 4 sets of; 18x8 31mm offset 8x6.5 bolt pattern. These seem to be oddball sizes and the few manufacturers I've...

Hello Greg, Thanks for the info. Yes, 1/8th octave seems odd. It might be stricktly a tire thing but we do look at that once in a while. Mostly we want to see 1/3 octave stuff but somewhere sometime there will be a request for more. At those prices someone is going to have to bump their...

Hello all, My company is interested in buying a new noise/vibration analyser and I was asked for my input. Having read Mr. Greg Locock's opinions on the subject (faq384-646,644) and being a little familiar with some of the systems available (Spectralab, H&K Pulse, Larson Davis), I thought I'd...
